How to install missing Perl modules on Debian

See Debian for information about Debian packages of Koha and its dependencies.

• Use aptitude to see if a prepackaged version exists
  • if the module name is Foo::Bar the packaged version will be called libfoo-bar-perl
  • so do 'aptitude search libfoo-bar-perl'
  • or just 'aptitude search foo-bar'
• Alternatively, install apt-file and use that:
  • To install and set up:
    • apt-get install apt-file
    • apt-file update
  • To search: apt-file search Foo/Bar.pm
  • This is more handy if you get an error giving an explicit filename that Perl can't find.
  • It is also a bit more reliable than the aptitude way for searching, since it does assume package names follow a pattern, or package descriptions contain the Perl module name.
• if found, use apt-get to install it
  • 'sudo apt-get install libfoo-bar-perl'
• if not found, install from CPAN
  • 'sudo dh-make-perl –install –cpan Foo::Bar'
• if that doesn't work for some reason
  • 'sudo cpan Foo::Bar'
