gentlemen: the folks on the gentoo mailing list did some further investigation into this f2c incompatibility with blas (boy, they are good!). apparently, this is likely to be a gcc bug:

    http://bugs.gentoo.org/show_bug.cgi?id=61042 they also have a fix for the particular show-stopper, which occurs in function blas.c. (a "const" addition to the parameters cures the problem.)

just in case you are still interested...
