perl5.18 port broken after last update

[Dr. Kyle Kneisl]

Hello.

As of the 15 September update to the Perl 5.18 port, it no longer builds 
for me or my associates.  The error message is below; this is the tail 
of the output where it appears to go awry:

===>  Installing for perl5-5.18.4_17
===>  Checking if perl5 already installed
===>   Registering installation for perl5-5.18.4_17 as automatic
[murmur] Installing perl5-5.18.4_17...
pkg-static: perl5-5.18.4_17 conflicts with perl5.18-5.18.4_17 (installs 
files into the same place).  Problematic file: 
/usr/local/share/licenses/perl5-5.18.4_17/catalog.mk
*** [fake-pkg] Error code 70

Stop in /usr/ports/lang/perl5.18.
*** [install] Error code 1

Stop in /usr/ports/lang/perl5.18.
*** [build-depends] Error code 1

What's odd here, of course, is the repeat of the version string 5.18 
twice in the new build (perl5.18-5.18-4_17), where that was not the case 
previously.  I assume that's a fatfinger somewhere, and the culprit.

Thanks for looking into it.
