one option is indeed to put special copies of tcl.h and friends into 
/usr/include (which as you mention would just #include their 
framework equivalents). then building with e.g. -F ~/Library/Tcl 
-framework Tcl will just work (/usr/include is included by default 
no?)

However makefiles not using TEA and expecting a standard 
/usr/include/tcl.h and -ltcl to map to /usr/lib/libtcl.dylib won't be 
happy anymore. The latter could be fixed with a symbolic link, but 
what about include files?

One solution would be to specify a constant like #define 
USE_TCL_FRAMEWORK in tclConfig.sh that signals the use of <Tcl/*> 
style includes for TEA compliant builds, and put modified copies of 
tcl.h et al. into /usr/include that have a block like
	#ifdef  USE_TCL_FRAMEWORK
	#include <Tcl/tcl.h>
	#else
	... standard tcl.h ...
	#endif
prepended, which should be easy to do with sed/awk/perl in a PBX 
shell script phase.

then non-TEA makefiles should still work fine. (e.g. one infamous 
example for this would be TclX, I had a bad enough time already 
getting it to build with the current setup where SCRIPT_LIBRARY isn't 
inside /usr like it expects...)

Cheers,

Daniel
