We really should have MacPorts libs be utilizable by projects that want to
put them on the App Store or use them any way they want to use them, if at
all possible.

The LC_VERSION_MIN_MACOSX issue is interesting.

There is lots of code in ld64 that appears designed to add this, and to
fall back on the DEPLOYMENT_TARGET to set it if it's not on the command
line, and to handle mismatches between the DEP target and the command line.

And yet I too can't see that chunk being added to dylibs either using xcode
ld64 or ld64-latest, whether building from source or downloaded from the

Something is amiss -- not sure it is a MacPorts issue, exactly, at this
moment. I await inspiration or insight...
