How do I change the @INC variable to use BioPerl?

I have successfully installed BioPerl.

When I try to use the objects I get an error cannot locate Bio.seq.pm in @INC .....

The "build" programs put everything in the "download" directory.

I am having trouble moving the files to /usr/bin and suspect that maybe adding the "download" directory to the @INC paths might be easier.

How can I fix this?

The variable @INC is defined when Perl is compiled and it is embedded in the binary code.

The @inc array can be changed by modifying the PERL5LIB variable, from the command line, like so:

export PERL5LIB=/home/foobar/code

You can add this to either your ~/.bashrc or ~/.bash_profile(the preferred location) to make this change permanent.

Additionally, you can use the following in your script code:

use lib '/home/foobar/code';
