One simple way to check that things are in the right place is to print out
the hard-coded @INC that perl looks through for libraries:
- % perl -e 'print join("\n",@INC)'
+ % perl -le 'print for @INC'
If this command lists any paths that don't exist on your system, then you
may need to move the appropriate libraries to these locations, or create
