;; Commentary:
;;
;; Standard build procedure for Perl packages using the "makefile
;; maker"---i.e., "perl Makefile.PL". This is implemented as an extension of
;; `gnu-build-system'. Cross-compilation is supported for some simple Perl
;; packages, but not for any Perl packages that do things like XS (Perl's FFI),
;; which makes C-style shared libraries, as it is currently not known how to
;; tell Perl to properly cross-compile.
;;
;; Code:
(define %perl-build-system-modules
;; Build-side modules imported by default.
`((guix build perl-build-system)
,@%gnu-build-system-modules))

"Return the default Perl package."
