In your .bashrc/.bash_profile/.profile, add:
- export PERL5LIB=~/site/perl/share/perl/5.8:~/site/perl/share/perl/5.8.4:~/site/perl/lib/perl5:~/site/perl/lib/perl/5.8.4
+ export PERL5LIB="$HOME/site/perl/share/perl/5.8:$HOME/site/perl/share/perl/5.8.4:$HOME/site/perl/lib/perl5:$HOME/site/perl/lib/perl/5.8.4"
+
+These locations may be different on your computer. For example, I use:
+
+ export PERL5LIB="$HOME/site/perl/lib/perl5:$HOME/site/perl/lib/perl5/site_perl/5.8.8:$PERL5LIB"
You probably want to add *~/site/perl/bin/* to your path, as well, since Ikiwiki's scripts are put in there.
