If I try building perl on a system without that same version of perl already installed, I get the following warning while building ext/POSIX Making POSIX (dynamic) Note (probably harmless): No library found for -lposix Note (probably harmless): No library found for -lcposix Can't locate auto/POSIX/autosplit.ix in @INC (@INC contains: ../../lib /opt/perl/lib/5.9.0/sun4-solaris /opt/perl/lib/5.9.0 /opt/perl/lib/site_perl/5.9.0/sun4-solaris /opt/perl/lib/site_perl/5.9.0 /opt/perl/lib/site_perl .) at ../../lib/AutoLoader.pm line 160. at POSIX.pm line 5 Writing Makefile for POSIX cp POSIX.pod ../../lib/POSIX.pod cp POSIX.pm ../../lib/POSIX.pm AutoSplitting ../../lib/POSIX.pm (../../lib/auto/POSIX) I'm not sure how long this one's been around. I see it both in maintperl and bleadperl. I think it's due to MakeMaker trying to get the version from POSIX.pm, and line 5 of POSIX.pm is C< use AutoLoader; >. -- Andy Dougherty doughera@lafayette.edu
