I've seen this a couple of times - e_wsfe is a Fortran I/O symbol from the gcc system and should be made available by libg2c. My guess if that you have inconsistencies in the compilers used, i .e. a different one was used for building the blas libraries by RH and by you for numpy. Try adding g2c to the list of libraries. There's a comment about it in the scipy FAQ: http://www.scipy.org/FAQ#head-26562f0a9e046b53eae17de300fc06408f9c91a8 Karol -- written by Karol Langner Wed Oct 11 09:35:15 CEST 2006 ------------------------------------------------------------------------- Using Tomcat but need to do more?
