How can you determine what Perl module is causing “undefined symbol: Perl_Tstack_sp_ptr?”

Question

I\'m trying to run a Perl script, but it is returning:

/usr/bin/perl: symbol lookup error: /usr/local/groundwork/perl/lib/5.8.8/x86_64-linux-thread-

Answer 1

I ran into this problem recently when I had a PERL5LIB environment variable defined in my login files, but they were pointing to a directory that was incompatible with the system-installed perl. This happened because the HOME filesystem is cross-mounted on lots of different machines where the perl installations are heterogenous. Deleting the environment variable solves the problem, and I'll find a better way to manage local libraries.
