I've just verified the fix works. There is only one small issue:

/usr/share/perl5/Encode/Makefile_PL.e2x from perl-devel is omitted from the
dependency scan:

* x86_64/perl-devel:
removed     PROVIDES perl-devel(x86-64) = 4:5.14.2-207.fc17
added       PROVIDES perl-devel(x86-64) = 4:5.14.2-208.fc17
removed     PROVIDES perl(MY)  
removed     REQUIRES perl >= 1:5.7.2

This is because `file' thinks it's C source code now. Former guess was `Perl5
module source, ASCII text'. But this is a regression in files magick database.
Reported as <https://bugzilla.redhat.com/show_bug.cgi?id=772651> against
`file'.
