Hi Jim,
the lapack libraries have a not standard location in
/usr/lib/lapack/
to allow anyone to install Atlas libraries with the same name 
in the standard 
/usr/bin 
and avoid a collision.

For this reason there are two shell startup files
/etc/profile.d/lapack.csh
/etc/profile.d/lapack.sh

to add /usr/lib/lapack/ at the end of the search path.
I suspect you have a redefinition of the PATH variable
in your own shell startup files that does not include
/usr/lib/lapack/

Could you add that and try again ?

The best way is to define the PATH to include /usr/lib/lapack.

For cygwin 1-5 the last version is octave 3.0.3-1, 
3.0-5 is a old version.

Cygwin-1.7 should go live in two weeks and it has 
octave-3.2.0-2 but the octave package works in exactly 
the same way so you will have the same PATH problem.
