adding the following to the portfile fixes the problem

platform darwin 8 { build.env-append MACOSX_DEPLOYMENT_TARGET=10.4 configure.env-append MACOSX_DEPLOYMENT_TARGET=10.4 }

[ryandesign (Ryan Carsten Schmidt)]

MACOSX_DEPLOYMENT_TARGET environment variables were added in r33373. This should not have been necessary anymore, however, since MacPorts 1.6 automatically sets these variables. In particuler, r33373 seems incorrect because it will result in MACOSX_DEPLOYMENT_TARGET being set to 10.4 on 10.4, and 10.3 on all other versions of Mac OS X (including 10.5).

I recommend removing the setting of MACOSX_DEPLOYMENT_TARGET from the portfile. If that's not possible, please explain why not. (MacPorts base should already be doing this automatically.)
