[f2py] problem finding shared library: libsvml.so

[Charles Seaton]

Hello,

I am attempting to use f2py with python2.6 on a CentOS 5.4 linux system 
(specifically:

Python 2.6.4 (r264, Nov 18 2009, 17:36:42)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2

As a first test, I have created a hello.f file (from the scipy f2py 
documentation):

C File hello.f
       subroutine foo (a)
       integer a
       print*, "Hello from Fortran!"
       print*, "a=",a
       end

And compiled using:

python2.6 /usr/bin/f2py -c -m hello hello.f

The hello.so shared library generates successfully, but when I try to 
load it into python2.6, I get the following error message:

 >> import hello
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: libsvml.so: cannot open shared object file: No such file or 
directory

Searching online for shared libraries and f2py turned up a numpy0.95 bug 
from 5 years ago, but nothing else.

I am at a loss as to how to solve this. Any assistance would be greatly 
appreciated.

thanks,
