# After reviewing the result from the previous step and making appropriate modifications, add it to <code>pkgs/top-level/perl-packages.nix</code>.

==Adding something without a Makefile.PL== | |||
The perlPackages.buildPerlPackage assumes a Makefile.PL to exist as part of the configurePhase. | |||
If no such file is present in the project you are building, it is easiest to add a Makefile.PL into the source yourself. | |||
The example below does so by adding it using the postPatch hook: | |||
<syntaxHighlight lang="nix"> | |||
postPatch = '' | |||
cat <<EOF > Makefile.PL | |||
use v5.10; | |||
use ExtUtils::MakeMaker; | |||
WriteMakefile( | |||
NAME => 'RevBank', | |||
VERSION_FROM => 'revbank', | |||
ABSTRACT_FROM => 'lib/RevBank.pod', | |||
EXE_FILES => [ 'revbank' ], | |||
); | |||
EOF | |||
''; | |||
</syntaxhighlight> | |||
The documentation for ExtUtils::MakeMaker can be found [https://perldoc.perl.org/ExtUtils::MakeMaker here]. | |||

Also keep in mind that <code>makePerlPath</code> would not resolve transitive dependencies of Perl packages. Hence if you want to just reference top-level packages, then use <code>makeFullPerlPath</code> which would recursively resolve dependency graph for you. | Also keep in mind that <code>makePerlPath</code> would not resolve transitive dependencies of Perl packages.
