Bugzilla Bug 80999

The Duke3D ebuild fails for reasons I don't understand. Apparently the current
Perl does not have a symbol called "My_perl" 

I sync and update my machine daily. 

Reproducible: Always
Steps to Reproduce:
Just attempt to build the program.
Actual Results:

I've found this, myself using perl 5.8.5 and also a friend using 5.8.6. As a 
workaround disabling the perl USE flag allows the game to compile correctly 

builds fine for me with USE=perl.  here's what I'm using:

[ebuild   R   ] dev-lang/perl-5.8.5-r5  +berkdb -debug -doc +gdbm -ithreads
-perlsuid

Does not work here with

[ebuild   R   ] dev-lang/perl-5.8.7-r3  +berkdb -build -debug +doc +gdbm
+ithreads -minimal -perlsuid

donsn't compile with
dev-lang/perl-5.8.6-r8  +berkdb -build -debug -doc +gdbm +ithreads -minimal
-perlsuid

Uhm, as I can see, all 3 people that encountered this bug have USE=ithreads set
for perl... Add a check for that use flag and be done with it? :)

A check for perl build with ithreads use flag disabled is in portage. Thanks
for report
