I am an inexperienced user. I have two different bioinformatics applications using different Perl libraries. I get the following error when trying to execute one of them:

/usr/bin/perl: symbol lookup error: /home/karen/.t_coffee/perl/lib/perl5/x86_64-linux-gnu-thread-multi/auto/Encode/Encode.so: undefined symbol: Perl_xs_apiversion_bootcheck

I understand that the app is being directed to the wrong Perl library, but I don't know how to fix the problem.

Thanks in advance.
