I updated my MacBook to Snow Leopard sometime last summer, and apparently it blew away my old version of Perl. This also blew away any modules I had installed, notably Text::BibTeX, which I use to parse BibTeX files to generate a webpage of papers. Today, I wanted to compare my BibTeX to the bbl file for my dissertation and see what things I forgot to cite.
Installation via CPAN failed (perl -MCPAN -e”install Text::BibTeX”), so I downloaded manually and the Makefile.PL failed because I don’t have a C compiler… because Snow Leopard blew away my previous install of Xcode I guess. So now I’m engaged in an (estimated) 20-minute install of Xcode from DVD to get gcc or equivalent to install manually.
After installing Xcode, I decided to try installing again via CPAN module, but it failed. In contrast, the manual install worked fine.
