 I see in the log:

 {{{
 Warning: xcodebuild exists but failed to execute
 }}}

 and

 {{{
 Warning: Xcode does not appear to be installed; most ports will likely
 fail to build.
 }}}

 Which causes "System cc" to be the compiler that's used:

 {{{
 DEBUG: Using compiler 'System cc'
 }}}

 Which causes at-spi2-core to fail to build with the universal variant:

 {{{
 lipo: /opt/local/var/macports/build
 /_opt_bblocal_var_buildworker_ports_build_ports_gnome_at-spi2-core/at-
 spi2-core/work/.tmp/cc3UStyY.out and /opt/local/var/macports/build
 /_opt_bblocal_var_buildworker_ports_build_ports_gnome_at-spi2-core/at-
 spi2-core/work/.tmp/ccyIbdDh.out have the same architectures (x86_64) and
 can't be in the same fat output file
 }}}

 Which causes wine to be unable to be installed.

 I am seeing this only on snowleopard-x86_64-legacy, not on
 snowleopard-i386-legacy nor snowleopard-x86_64 nor the other workers.

 It was my intention to set up all the buildbot workers the same way.

 This problem appears to have started in
 [https://build.macports.org/builders/ports-10.6_x86_64_legacy-
 builder/builds/6874 build 6874].
 [https://build.macports.org/builders/ports-10.6_x86_64_legacy-
 builder/builds/6873 Build 6873] says:

 {{{
 DEBUG: Using compiler 'Xcode GCC 4.2'
 }}}

 but as of [https://build.macports.org/builders/ports-10.6_x86_64_legacy-
 builder/builds/6874 build 6874] we start to see:

 {{{
 DEBUG: Using compiler 'System cc'
 }}}

 I don't know what caused this.

 We ran into the same problem on the previous Snow Leopard buildbot worker
 a couple years ago; see #46099. I couldn't figure out what caused that
 either; it solved itself.
