Comment(by mta@…):

 I just attached (twice, due to a browser hiccup) a patch to use the
 muniversal port group to build 32/64 universal versions of apr and apr-
 util. I don't think it is possible to build ppc/intel universal versions
 on one machine since the configure script needs to run programs in the
 target architecture.

 In order to make this work I had to make one small change to muniversal.
 It adds a merger_build_env array similar to the merger_configure_env
 array.  The patch to muniversal also fixes a minor typo in a debug
 message.

 I added code to the apr portfile that knows how to merge make files and
 shell scripts.  This could be generalized and moved into muniversal.
 Perhaps the current merger_dont_diff array could be generalized to a
 merger_diff_how array with one value being "dont" and others being things
 like "header file", "make file", "shell script", or whatever.

 The two copies of the attachment are identical.  I would delete one of
 them, but I can't see a way to do it.
