I believe it was only recently recompiled for libc6 (just before code
freeze). Try
ftp://ftp.debian.org/pub/debian/hamm/hamm/binary-i386/devel/
lapack-dev_2.0.1-2.1.deb

lapack-dev is a fortran library. The consequence of this is that on
Linux, Irix, and perhaps other systems you need to call function_() instead
of function(), and pass all values by address. For example:
Matrix& Matrix::invert() {
int n=4,ipiv[4],info;
float work[4];
sgetrf_(&n,&n,m,&n,ipiv,&info); // float m[4][4]
sgetri_(&n,m,&n,ipiv,work,&n,&info);
return *this;
}
Lapack++ hasn't been packaged yet, but would be welcome. The successor,
NTL, might be a better time investment. http://math.nist.gov/tnt/

I used the old lapack-dev for a while in a mixed libc5/libc6 environment,
but wouldn't suggest trusting it for production work. If you compile with
the libc5 gcc-altdev package it should be safe.
