With any luck, someone has seen this problem before and can fix it easily. I don t seem to be able to find the fix by searching, but the search terms feel like they re either too general or too specific.
I was trying to install some perl software on a debian lenny system that was upgraded from etch (and previously from sarge). After installing the dependencies, I started getting errors like this:-
$ perl -MYAML::Syck -e print
Can't locate YAML/Syck.pm in @INC (@INC contains:
/usr/local/lib/perl5/5.10.0/i686-linux /usr/local/lib/perl5/5.10.0
/usr/local/lib/perl5/site_perl/5.10.0/i686-linux
/usr/local/lib/perl5/site_perl/5.10.0 .).
BEGIN failed--compilation aborted.
Update: Well done to Raphael who spotted the local that I d overlooked. D oh! Now to see if I can discover where that came from.
Update 2: Also thanks to Florian who emailed in at about the same time (I don t read my email as much as my website dashboard, usually).
Then I discovered that the debian mirror being used (which is in the same city, and in a nearby network) is marked as bad on
the health check. I switched mirrors to a known-good one that I ve used for other systems recently, but no joy.
I think a key symptom is this bit near the end of the output of
perl -V:

/usr/local/lib/perl5/site_perl/5.10.0
Our good systems show a December compiled at date and a much longer @INC list. I ve tried reinstalling pretty much every package I think might be connected, including libc6, libperl5.10, perl, perl-base and perl-modules (those last four are all version 5.10.0-19). I really don t want to reinstall the whole system because it s behind an irritating firewall that will make it a 10-hour round-trip site visit. I m currently hunting and removing obsolete packages to try to make sure they re not causing problems, because I m running out of straws to clutch at.
How would you recover a debian system from this?
