then don't worry about the warning message. The extension
Makefile.PL goes looking for various libraries needed on various
systems; few systems will need all the possible libraries listed.
-For example, a system may have -lcposix or -lposix, but it's
-unlikely to have both, so most users will see warnings for the one
-they don't have. The phrase 'probably harmless' is intended to
-reassure you that nothing unusual is happening, and the build
-process is continuing.

On the other hand, if you are building GDBM_File and you get the
message
read your message. Your message will get relayed to over 400
subscribers around the world so please try to keep it brief but clear.
+If the bug you are reporting has security implications, which make it
+inappropriate to send to a publicly archived mailing list, then please send
+it to perl5-security-report@perl.org. This points to a closed subscription
+unarchived mailing list, which includes all the core committers, who be able
+to help assess the impact of issues, figure out a resolution, and help
+co-ordinate the release of patches to mitigate or fix the problem across all
+platforms on which Perl is supported. Please only use this address for security
+issues in the Perl core, not for modules independently distributed on CPAN.
