Yes. 

"fink show-deps fftw3" will show you what packages
are required at build 
or run time.  Probably "fink show-deps
fftw3-shlibs" will be more 
relevant in this case.
"fink dumpinfo -fconfigureparams fftw3" will show
you the flags that are 
fed into its configure script (and that also covers the
-shlibs).

Otherwise you can look at the package description file--the
location of 
which you can determine via "fink dumpinfo -finfofile
fftw3"

Or you can move /usr/local temporarily while you build gdl
and its 
dependencies.
