I am running 10.2 and am trying to upgrade to Perl 5.8.0 and am getting a bit of resistance from the Configure script. It seems to have this issue with gcc: Code: Use which C compiler? [cc] Checking for GNU cc in disguise and/or its version number... try.c:1:19: stdio.h: No such file or directory *** WHOA THERE!!! *** Your C compiler "cc" doesn't seem to be working! You'd better start hunting for one and let me know about it. I am new to OS X, but not Perl nor UNIX, and I can't get this to work! I can't detect anything wrong with gcc (v3.1 via Apple Developer Tools). Has anyone else seen this and/or have any advice?
