My bad, when I saw enable-type-prefix, I thought these were generic
instructions telling you to indicate your architecture for platform
dependent optimizations.  That is why I substituted the
'--enable-i386-hacks' in the place of '--enable-type-prefix' in my
configure statement.

Now when I configure with 
# configure --enable-threads --enable-float  --enable-type-prefix --enable-i386-hacks
I get the sfftw libs.  

Thanks for the help,
JDH
