dh_perl - Man Page

calculates Perl dependencies and cleans up after MakeMaker


dh_perl [debhelper options] [-d] [library dirs ...]


dh_perl is a debhelper program that is responsible for generating the ${perl:Depends} substitutions and adding them to substvars files.

The program will look at Perl scripts and modules in your package, and will use this information to generate a dependency on perl or perlapi. The dependency will be substituted into your package's control file wherever you place the token ${perl:Depends}.

dh_perl also cleans up empty directories that MakeMaker can generate when installing Perl modules.



In some specific cases you may want to depend on perl-base rather than the full perl package. If so, you can pass the -d option to make dh_perl generate a dependency on the correct base package. This is only necessary for some packages that are included in the base system.

Note that this flag may cause no dependency on perl-base to be generated at all. perl-base is Essential, so its dependency can be left out, unless a versioned dependency is needed.


By default, scripts and architecture independent modules don't depend on any specific version of perl. The -V option causes the current version of the perl (or perl-base with -d) package to be specified.

library dirs

If your package installs Perl modules in non-standard directories, you can make dh_perl check those directories by passing their names on the command line. It will only check the vendorlib and vendorarch directories by default.
