>Description:
I'm using pkgsrc on a Macbook (I used MacPorts previously,) and I wanted to use 
chat/weechat as my IRC client.  However, in my previous installation I used 
WeeChat's Perl plugin, and now in pkgsrc chat/weechat it has does not have Perl 
plugin enabled, due to this bit in the Makefile:

CONFIGURE_ARGS+=        --disable-ruby --disable-perl --disable-aspell

I understand that this line also stops Ruby support, which would have been nice 
too.  So, I would like chat/weechat to have optional Perl and Ruby support just 
like what it currently does for Python and Lua (as seen in `bmake 
show-options`.)

>How-To-Repeat:
1. cd pkgsrc/chat/weechat
2. bmake install clean clean-depends
3. weechat-curses
4. '/perl' or '/ruby' on WeeChat's command/chat buffer
5. Output from #4: 'WeeChat Error: unknown command "perl" (type /help for 
help).'  This should not be the case if Perl support was enabled.

>Fix:
1. Remove `--disable-{perl,ruby}' in Makefile's CONFIGURE_ARGS
2. Add a block in options.mk to support Perl and Ruby, similar to Python:

.if !empty(PKG_OPTIONS:Mperl)
.include "../../lang/perl5/buildlink3.mk"
CONFIGURE_ARGS+=        --enable-perl
PLIST.python=           yes
.else
CONFIGURE_ARGS+=        --disable-perl
.endif

.if !empty(PKG_OPTIONS:Mruby)
.include "../../lang/ruby/buildlink3.mk"
CONFIGURE_ARGS+=        --enable-ruby
PLIST.python=           yes
.else
CONFIGURE_ARGS+=        --disable-ruby
.endif

3. Double check.  I'm probably missing something here.
