[PD] flext/sc4pd some feedback

[Thomas Grill]

Hi Peter,
it seems sc4pd still provides the old makefiles which have been  
superseded by the flext build system.
With that you make sc4pd with "sh yourpathtoflext/build.sh pd gcc",  
just as you build flext itself. (see build.txt in the flext package)
This _should_ work for linux. I just realized that sc4pd is not  
portable because endian.h is included but not available on OSX for  
example.

With the old makefiles, you would have to change the -lflext_d to  
-lflext-pd_d, although i'm wondering why the debug version is used. The  
normal deployment build would use -lflext-pd

best greetings,
Thomas
