 Well, the port in its present for is just unusable. I tried to build
 `gtest` as `+universal` on 10.6.8 (Xcode 4.2), it failed to link:

 Notice:
 {{{
 /opt/local/lib/libcxx/libc++.dylib, file was built for unsupported file
 format which is not the architecture being linked (i386)
 }}}

 Checking that, indeed:
 {{{
 10:~ svacchanda$ port provides /opt/local/lib/libcxx/libc++.dylib
 /opt/local/lib/libcxx/libc++.dylib is provided by: macports-libcxx
 10:~ svacchanda$ file /opt/local/lib/libcxx/libc++.dylib
 /opt/local/lib/libcxx/libc++.dylib: Mach-O 64-bit dynamically linked
 shared library x86_64
 }}}

 However, it is supposed to be universal:
 {{{
 10:~ svacchanda$ port -v installed macports-libcxx
 The following ports are currently installed:
   macports-libcxx @11.1.0_0 requested_variants='' platform='darwin 10'
 archs='x86_64' date='2023-11-08T05:22:47+0800'
   macports-libcxx @11.1.0_0+universal (active)
 requested_variants='+universal' platform='darwin 10' archs='i386 x86_64'
 date='2024-01-26T03:23:04+0800'
 }}}

 `macports.conf` has `x86_64 i386` for universal_archs, nothing exotic.
