if an ebuild uses the builder style, the eclass should handle the DEPEND for it: if [[ ${style} = "builder" ]] ; then DEPEND="${DEPEND} dev-perl/module-build" fi also, if module-build isnt emerged, and you try to emerge a perl module which needs it, the eclass doesnt fail at all: root@spyro 0 ~ # emerge sdl-perl Calculating dependencies ...done! >>> emerge (1 of 1) dev-perl/sdl-perl-2.1.2 to / >>> md5 files ;-) ChangeLog >>> md5 files ;-) metadata.xml >>> md5 files ;-) sdl-perl-1.20.3.ebuild >>> md5 files ;-) sdl-perl-2.1.2.ebuild >>> md5 files ;-) files/digest-sdl-perl-1.20.3 >>> md5 files ;-) files/digest-sdl-perl-2.1.2 >>> md5 src_uri ;-) SDL_Perl-2.1.2.tar.gz >>> Unpacking source... >>> Unpacking SDL_Perl-2.1.2.tar.gz to /var/tmp/portage/sdl-perl-2.1.2/work >>> Source unpacked.

I got sidetracked in real life, but work for making module::build as a "core" part of the eclass is already under way. Arch's have tested, and forthcoming is a change to the eclass to handle Build.pl scripts internally.

Smile - does now.
