have /usr/you/include/gdbm.h and /usr/you/lib/libgdbm.a. You
still have to add -I/usr/you/include to cc flags, but you have to take
an extra step to help Configure find libgdbm.a. Specifically, when
process, you can answer a question with &-d and Configure
will use the defaults from then on.

+The directories under site_perl are empty, but are intended to be used
for installing local or site-wide extensions. Perl will automatically
look in these directories.
For example, you can replace the rand() and srand() functions in the
perl source by any other random number generator by a trick such as the
-following:
+following (this should all be on one line):
- sh Configure -Dccflags='-Drand=random -Dsrand=srandom'
+ sh Configure -Dccflags='-Dmy_rand=random -Dmy_srand=srandom' \
+ -Drandbits=31
-or by adding -Drand=random and -Dsrand=srandom to your ccflags
-at the appropriate Configure prompt. (Note: Although this worked for
-me, it might not work for you if your system's header files give
-different prototypes for rand() and random() or srand() and srandom().)
+or you can use the drand48 family of functions with
+
+ sh Configure -Dccflags='-Dmy_rand=lrand48 -Dmy_srand=srand48' \
+ -Drandbits=31
+
+or by adding the -D flags to your ccflags at the appropriate Configure
+prompt. (Read pp.c to see how this works.)
You should also run Configure interactively to verify that a hint file
doesn't inadvertently override your ccflags setting. (Hints files
will offer to use that hint file.
Several of the hint files contain additional important information.
-If you have any problems, it is a good idea to read the relevant hint
-file for further information. See hints/solaris_2.sh for an
-extensive example.

can also edit cflags directly, but beware that your changes will be
lost the next time you run Configure.
-To change the C flags for all the files, edit config.sh

If you can successfully build miniperl, but the process crashes
during the building of extensions, you should run
- make minitest
+ make minitest
to test your version of miniperl.
Installperl will also create the library directories $siteperl and
$sitearch listed in config.sh. Usually, these are something like
- /usr/local/lib/perl5/site_perl/5.005/share
+ /usr/local/lib/perl5/site_perl/5.005
/usr/local/lib/perl5/site_perl/5.005/archname
where archname is something like sun4-sunos. These directories

- $sitelib /usr/local/lib/perl5/site_perl/5.005/share
+ $sitelib /usr/local/lib/perl5/site_perl/5.005
while the directories searched by version 5.005_01 will be
$archlib /usr/local/lib/perl5/5.00501/archname
- $privlib /usr/local/lib/perl5/5.00501/share

- $sitelib /usr/local/lib/perl5/site_perl/5.005/share
+ $sitelib /usr/local/lib/perl5/site_perl/5.005
When you install an add-on extension, it gets installed into $sitelib (or
$sitearch if it is architecture-specific). This directory deliberately
the distribution. Alternatively, you can use the perlbug program that
comes with the perl distribution, but you need to have perl compiled
before you can use it. (If you have not installed it yet, you need to
-run C<./perlbug -Ilib> instead of a plain C<perlbug>.)

You might also find helpful information in the Porting directory of the
perl distribution.

feedback and additions from the perl5-porters@perl.org folks.
