I had the same problem. "BN_mod_exp_mont" is in libcrypto,but isn't
visible from librsaINTL.so because libcrypto is loaded in conjunction
with the load of /usr/local/libexec/apache/libssl.so via dlopen() .
The man page to dlopen states " The symbols exported by objects added
to the address space by dlopen() can be accessed only through calls
to dlsym()".
I have solved the problem with the attached patch. It adds libcrypto
to the list of linked libs.
Maybe there is a better solution,who knows ?
Regards
Dirk
