AIX notes

Spheral++ builds as a series of dynamically loading libraries, which requires that the loader be able to resolve where these libraries are at load time. Unfortunately we are currently having some problem with the rpath on AIX, so the user must explicitly set their LIBPATH environment variable in order for the loader to perform this resolution correctly at run time. The Spheral++ libraries are installed in topdir /lib/python2.4/site-packages/Spheral, where topdir is the directory where you installed the Spheral++ source. On AIX set your LIBPATH environment variable to this path when you want to run Spheral++.
