Hi Mike,
I was able to compile the flext stuff, but when I get to 'vasp', it goes thru everything, except the final linking stage where it complains:
ld: Undefined symbols: _BlockMoveData _BlockZero make: *** [pd-darwin/vasp.pd_darwin] Error 1
these are part of the Carbon framework which is part of the PSX system. I'm a bit surprised that this is not covered in the Makefile you are using. I attach the files used now for the cvs version. These should also work. If not, you coulda also edit your Makefile and add a "-framework Carbon" as an option to the linker command.
best greetings, Thomas
