I am trying to install postgreSQL with perl support on a Slackware Linux
9.1. I have compiled perl with shared libraries, the rest of the settings
default. Then I configured postgres with --with-perl and it worked fine.
  But when I am executing 'make' I get an error: plperl no such file or
directory. I have tried everything. Please help!
