Description
When attempting to build a program that uses a particular clapack function, the linker complains that the symbol is undefined. In particular, I get the following error message:
$ gcc-mp-4.3 -I/opt/local/include -L/opt/local/lib -lcblas -llapack -latlas main.c
Undefined symbols:
"_clapack_dgesv", referenced from:
_biasfilter_update in cc65P2Zm.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

I'm having issues building atlas@3.8.2, what installed version do you actually have?

I have this symbol in my build of atlas. Just compiled from an updated port repository (3.8.3):
% nm /opt/local/lib/liblapack.dylib | grep _clapack_dgesv 004425e0 T _clapack_dgesv
Could you verify you're running the most recent version and possibly provide sample source to reproduce the problem with?

Make sure you're using the latest build. Also try using the full path to the macports lapack library. The lookup error and lack of that exact symbol from the incomplete API that apple provides was the incentive for my reworking of the macports atlas port.
