15 # way to do that is to invoke Configure with

107 containing your C compiler is before /usr/ucb in your PATH.

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

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