You may need to carry out some system configuration tasks before
running the Configure script for Perl.

Some people have reported encountering "Out of memory!" errors while

For successful testing you may need to turn on the sticky bit for your
world readable /tmp directory if you have not already done so (see man chmod).

"Out of memory!" messages during the build of Perl are most often fixed
by re building the GNU make utility for OS/390 from a source code kit.

header /usr/include/sys/socket.h.

The `make test` step runs a Perl Verification Procedure, usually before
installation. You might encounter STDERR messages even during a successful
Recent perl test suite is quite memory hunrgy. In addition to the comments
above on memory limitations it is also worth checking for _CEE_RUNOPTS
in your environment. Perl now has (in miniperlmain.c) a C #pragma

+=head2 Installation Anomalies with Perl on OS/390
The installman script will try to run on OS/390. There will be fewer errors
if you have a roff utility installed. You can obtain GNU groff from the
Redbook SG24-5944-00 ftp site.
-=head2 Usage Hints
+=head2 Usage Hints for Perl on OS/390
When using perl on OS/390 please keep in mind that the EBCDIC and ASCII
character sets are different. See perlebcdic.pod for more on such character
rlogin or telnet client. Try to avoid older 3270 emulators and ISHELL for
working with Perl on USS.

There appears to be a bug in the floating point implementation on S/390
systems such that calling int() on the product of a number and a small
