9 # If perl fails tests that involve dynamic loading of extensions, and
10 # you are using gcc, be sure that you are NOT using GNU as and ld. One
11 # way to do that is to invoke Configure with
13 # sh Configure -Dcc='gcc -B/usr/ccs/bin/'
15 # (Note that the trailing slash is *required*.)
16 # gcc will occasionally emit warnings about "unused prefix", but
17 # these ought to be harmless. See below for more details.
24 # Avoid all libraries in /usr/ucblib.

124 NOTE: Your system does not have /dev/fd mounted. If you want to
125 be able to use set-uid scripts you must ask your system administrator
133 # See if libucb can be found in /usr/lib. If it is, warn the user
134 # that this may cause problems while building Perl extensions.

166 NOTE: Your PATH points to GNU make, and your GNU make has the set-group-id
167 bit set. You must either rearrange your PATH to put /usr/ccs/bin before the
168 GNU utilities or you must ask your system administrator to disable the
169 set-group-id bit on GNU make.
