I wasn't specific enough.

1 - ... using standard rpms, not a custom install
2 - ... building as well as executing
3 - ... just modifying the makefile to point to different headers and so

I.e., do the headers both go into /usr/include/openssl (which would clash)?

Do the .so's both have the same name - libcrypto.so?

It already works with a custom install and makefile.
