I suspect you are right.  I just ran into a similar problem building another
package that uses libtool.  The only "non-standard" flag I passed to
configure when building gcc was --disable-shared, but I don't see
how that would affect the search path for libraries.  libtool does it's own
searching and I don't think it cares where gcc looks.  But again, I know
very little about libtool, mostly just from looking at sh -x output.

Does anyone have any insight as to how libtool finds libraries?  Why 
can't it just pass -lltdl to the linker like the compile command told it to?
