Comment (by nicos@…):

 With the future release of MacPorts 2.3.0, where this issue would become
 widespread to all users, I patched cmake-1.0 with the last patch, where
 the variables CMAKE_OSX_SYSROOT and CMAKE_OSX_DEPLOYMENT_TARGET are set in
 the script, for the present case where ${configure.sdkroot} is not set.
 The patch from Ryan for the case where ${configure.sdkroot} is set, in
 conjunction with possible changes in portconfigure-1.0.tcl is also
 included just in case.

 Committed in r119436. I do not close the ticket yet, as I am not
 completely sure that this patch would solve all issues.
