I am using scipy from debian packages, so I did not compile it. The ldd
command on either vode.so or my share object from f2py gives the
following ouput :
        ldd /usr/lib/python2.5/site-packages/scipy/integrate/vode.so
        	linux-gate.so.1 =>  (0xb7f25000)
        	libblas.so.3gf => /usr/lib/atlas/libblas.so.3gf (0xb7b83000)
        	libgfortran.so.3 => /usr/lib/libgfortran.so.3 (0xb7ad1000)
        	libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb7aab000)
        	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7a9e000)
        	libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb7943000)
        	/lib/ld-linux.so.2 (0xb7f26000)

You may see that on this ticket, I've provided an example of small
computation where the solver reach the mxstep number of iteration, but
the error message is nicely displayed. The small example is also written
in fortran and compiled with f2py in a identical manner as I have done
with my study case...
