I can remember that problem - it is connected to the way how global  
variables (like garray_class, s_float etc.) in Pd are defined for the  
linker.
I must have found a solution once....

The flext-build output seems to indicate a c++ namespace problem which  
should not be too hard to fix.
The autoconf output seems different, probably a mixture of problems.

i'm not sure if i can spare any time for that soon but it's good to  
know the weak spots.

all the best,
Thomas
