I don't quite understand the question.  So tclpd.pd_darwin is a bundle/plugin that is linking to the Tcl framework using "-framework Tcl"  That Tcl 8.5.10 framework is built using:

export CFLAGS="-arch ppc -arch ppc64 -arch i386 -arch x86_64 \
 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.4"
make -C tcl/${BUILD_DIR} deploy

That Tcl.framework is installed into /Library/Frameworks.
