Comment(by srm@…):

 I had the same problem here on Snow Leopard.
 Set build_arch to i386 in macports.conf and it didn't work.
 I've added the following lines to the Portfile's post_patch section

 {{{
         reinplace "s:CFLAGS = :CFLAGS = -arch i386:g"
 ${worksrcpath}/configs/darwin
         reinplace "s:CXXFLAGS = :CXXFLAGS = -arch i386:g"
 ${worksrcpath}/configs/darwin

         #set correct flags for the AppleBuild
         reinplace "s:GL_CFLAGS=:GL_CFLAGS=-arch i386 :g"
 ${worksrcpath}/../AppleSGLX-57/Makefile
         reinplace "s:GL_LDFLAGS=:GL_LDFLAGS=-arch i386 :g"
 ${worksrcpath}/../AppleSGLX-57/Makefile
         reinplace "s:\$\(CC\) tests/glxinfo:\$\(CC\) -arch i386
 tests/glxinfo:g" ${worksrcpath}/../AppleSGLX-57/Makefile
         reinplace "s:\$\(CC\) tests/glxgears:\$\(CC\) -arch i386
 tests/glxgears:g" ${worksrcpath}/../AppleSGLX-57/Makefile
 }}}

 It works now. Probably due to "use_config no" there's no hope using normal
 configure._.append and the different build's didn't use the correct
 C/XXFlags
