Re^3: Trouble installing DBD::Pg

The error message is the clue. You've got conflicting mismatching files. Either get rid of them (delete/overwrite), or install to a different location, or call the right perl binary ($PATH), or sanitize your environment variables (PERLLIB/PERL5LIB).

Thanks for your reply. You give my very good advice. Nevertheless, it doesn't answer my question. My question was: "Why does it works on the second run of the script?". Thats what I'm trying to figure out.
