Details:

$cat main.c
int gsl_linalg_QR_decomp();
int main() {
  return 0;
}
$gcc main.c -lgsl
/usr/lib64/gcc/x86_64-suse-linux/4.4/../../../../lib64/libgsl.so: undefined
reference to `cblas_csyrk'
(and more)

In gentoo the problem is fixed. (see patch)

The patch also includes the possibility to use an external cblas
implementation, which is very very useful on HPC machines with an optimized
version of cblas.
