Comment(by 10.50@…):

 Postgresql83 will not build universal files with the default Portfile. I
 encounter three problems:

 1. Build process uses ld directly, and ld cannot handle more than one arch
 at a time;
 2. SIZEOF_UNSIGNED_LONG in src/include/pg_config.h does not change
 according to arch;
 3. On my late 2008 MacBook with gcc-4.0.1, I cannot build postgres83
 because gcc-4.0 crashes with a bus error at some point (I have opened a
 ticket in the Apple bugtracker for this).

 I have attached a fix in three files:

 1. A ld.sh shell script that replaces direct ld calls by a tool that
 analyses the line and extracts the output file out of the args;
 2. A modified Portfile that:
         a. Appends to the ld.sh the necessary calls to ld with the correct
 archs and a final call to lipo to join the separate .o files;
         b. Alters the src/Makefile.global file to replace direct ld calls
 by calls to our ld.sh script tool;
         c. Defines a universal variant and a gcc42 variant to avoid the
 3rd problem cited above;
 3. A patch file to fix problem #2, patch applied after the configuration
 phase.

 The ld.sh and patch_pg_config_h should be stored in a ${portpath}/files
 subdirectory.

 Please test and tell me.
 V.
