update of devel/swig

[Takahiro Kambe <taca%back-street.net@localhost>]

Hi,

I'll update devel/swig package to 1.3.36 from current 1.3.31.

swig 1.3.36 isn't latest release but devel/swig/Makefile clams that
1.3.37 break gnuradio.  And here is additional comment which will be
added to devel/swig/Makefile:

#
# x11/wxruby 2.0.1 requires 1.3.32 for Ruby 1.8 and 1.3.37 for
# Ruby 1.9.  And SWIG 1.3.39 introduced some incompatibility
# with wxRuby, sigh.
#

x11/wxruby isn't imported yet but it needs newer swig package.

Best regards.
