Why won't Eclipse recognize $PERL5LIB?

I followed BioPerl manual: I cloned a fresh copy of bioperl-live under ~/src then added the following line to my ~/.profile (I'm using Ubuntu):

export PERL5LIB="$HO开发者_运维问答ME/src/bioperl-live:$PERL5LIB"

However,BioPerl modules are not recognized in Eclipse, e.g.:

Can't locate Bio/Tools/GFF.pm in @INC (@INC contains: 
 /home/dave/workspace/.metadata/.plugins/org.epic.debug 
 /home/dave/workspace_workspace/mars/scripts/lib 
 /etc/perl 
 /usr/local/lib/perl/5.10.1 
 /usr/local/share/perl/5.10.1 
 /usr/lib/perl5 
 /usr/share/perl5 
 /usr/lib/perl/5.10 
 /usr/share/perl/5.10 
 /usr/local/lib/site_perl )

What do I miss?

~/.profile is read when you log in. To use that setting until the next time you log in, start a terminal, run the export PERL5LIB=… line, then start Eclipse or any other BioPerl-using program from that terminal.
