Fedora's minimal build root contains perl. There is a reasonable request <https://bugzilla.redhat.com/show_bug.cgi?id=1158860> to remove the perl in order to minimize the build root. (The x86_64 F25 build root occupies 527 MB now, 20 MB of that are perl packages.) The reason why perl is there is the rpm-build package. The Requires dependency tree looks like: rpm-build perl-generators perl(:MODULE_COMPAT_5.22.1) perl(Fedora::VSP) perl perl-macros system-rpm-config (a Provide) redhat-rpm-config perl-srpm-macros While perl-srpm-macros's presence is intended, perl-generators' presence is unwanted. On technical level, the reason is the rpm-build binary package requires perl-generators explicitely. It's there for backward compatibility. Simply removing the dependency removes perl from minimal build root. But the compatibility is important. Without perl-generators in a build root no Perl dependencies are generated into binary packages. To fix it, every Perl package must build-require perl-generators.
Might it not be easier to use the newly-allowed boolean dependencies, e.g. in rpm-build something like this:
Requires: (perl-generators if perl-libs) Paul. -- Fedora Extras Perl SIG http://www.fedoraproject.org/wiki/Extras/SIGs/Perl perl-devel mailing list perl-devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/perl-devel@xxxxxxxxxxxxxxxxxxxxxxx
