 After applying the patch from #37418 to get past the error in Leopard's
 system headers, the build fails with:

 Based on official documentation, my understanding is that [http://www
 .ruby-doc.org/core-1.8.6/IO.html#method-i-getc in ruby 1.8.x, "getc" gets
 a byte] (1.8.6 documentation) while [http://www.ruby-
 doc.org/core-1.9.3/IO.html#method-i-getc in ruby 1.9.x, "getc" gets a
 character] while [http://www.ruby-
 doc.org/core-1.9.3/IO.html#method-i-getbyte "getbyte" gets a byte] (1.9.3
 documentation).

 The question mark is 1.8.7, whose documentation [http://www.ruby-
 doc.org/core-1.8.7/IO.html#method-i-getbyte has a link in the sidebar for
 "getbyte"] but which takes you to the definition of "getc", which appears
 twice. Snow Leopard, Lion and Mountain Lion ship with ruby 1.8.7 and the
 port builds there, so it seems (and the [http://svn.ruby-
 lang.org/repos/ruby/tags/v1_8_7/NEWS ruby 1.8.7 NEWS file] confirms) that
 in ruby 1.8.7 "getbyte" is a compatibility alias for "getc".

 Leopard has ruby 1.8.6 and Tiger has ruby 1.8.2. It seems the most correct
 thing to do, if you want to get a byte (which I assume is what the code in
 Source/JavaScriptCore/offlineasm/offsets.rb wants to do), is to check the
 ruby version, and use "getc" on ruby 1.8.x and earlier ande "getbyte" on
 ruby 1.9.x and later. I don't know enough ruby to be able to do that. For
 now, since all versions of OS X that MacPorts runs on today (10.4 through
 10.8 inclusive) have ruby 1.8.x, we could get away with unconditionally
 changing "getbyte" to "getc".

 I verified that changing "getbyte" to "getc" allows webkit-gtk @1.10.2 to
 build on Leopard.
