Regexp::Grammars module and dependent modules do not work with perl-5.18
(https://rt.cpan.org/Public/Bug/Display.html?id=87880, bug #992666).

It was being solved for a long time
https://rt.perl.org/rt3//Public/Bug/Display.html?id=116823, and it seems to
have been solved int the blead
http://www.nntp.perl.org/group/perl.perl5.porters/2013/07/msg204660.html,
http://www.nntp.perl.org/group/perl.perl5.porters/2013/08/msg206163.html.

Perl 5.18 (F≥20) is affected, e.g perl-5.18.1-288.fc21.x86_64.

--- Comment #1 from Petr Pisar  ---
There is nothing interesting in maint-5.18
(f4b15169f09b515c4765903d629c5125f9070e4a) after v5.18.1. However the
discussion highlights two commits worth of back-porting:

The `reparse compile-time /(?{})/ in right scope' patch does not seem to be
enough.

Is there anything I can do about this? I'm not good at fixing Perl bugs, but
people are filing bugs against slic3r and that bothers me.

Not much. You can troll on upstream list and ask when they are going to release
fixed version (or at least fix it the development tree because I'm not aware of
any fix).

I was SO wrong and slic3r now builds and works. This issue is still present,
but it is no longer a priority for me.

I just took a look at this again and it appears that perl-Regexp-Grammars will
work with perl 5.18.4.  If I remove if test that has the module croak with the
"perl 5.18 is unsupported" message, it will pass all the tests.  Also a couple
of programs I have locally appear to work fine.

I've asked the author of the module if he knows of anything else that will
prevent this module working on 5.18.4.  Assuming he doesn't know of anything, I
can upgrade perl-Regexp-Grammars in F21 to version 1.038 to match rawhide.
