-----------------------------------+----------------------------------------
 After a port selfupdate and port upgrade outdated, I installed {{{gcc45}}}
 successfully. Then, I installed {{{openmpi
 @1.5.4_0+gcc45+progressthreads+threads}}} after applying the patch in
 ticket #31244 to its Portfile. With these preparations, I tried to build
 Boost 1.47.0 using the following command to specify the variants:
 {{{
 sudo port -v install boost +debug +openmpi +python27 +regex_match_extra
 }}}
 I get the following error:

 The full build log is attached. I've been able to build successfully the
 boost port leaving out the openmpi variant:
 {{{
 sudo port -v install boost +debug +python27 +regex_match_extra
 }}}
 As indicated in the summary, I observed this behavior under Mac OS X Lion
 10.7.2 with Xcode 4.2.
