Description of problem:
blas,lapack are compiled with g77 - and hence have a dependency on
-lg2c - which is part of libf2c package

Version-Release number of selected component (if applicable):
blas-3.0-22, lapack-3.0-22

How reproducible:
Always

Steps to Reproduce:
1. install blas (for eg: yum install blas)
2.
3.
    

Actual Results:   /usr/lib/libg2c.so.0 is not installed (because there
is no depencency from blas to libf2c

Expected Results:  the following packages should be installed 
libf2c
blas

Additional info:

Could you add in the pacakge depencency between 'blas' and 'libf2c' 
because - this depencency is real - and without -lf2c -lblas is not
useable

Also, additionally - a build dependency can be added for gcc-g77 - as
without this package (i.e without g77)  lapack.src.rpm cannot be compiled
