Hello! Since 5.2 AIX supports /dev/random and /dev/urandom. Openssl don't use it because the select system call works different on AIX than on linux.
As described in the following URL, the select system call expects the number of file describtors as first parameter in AIX. Linux expects the highst numbered fd +1. http://publibn.boulder.ibm.com/doc_link/en_US/a_doc_lib/libs/commtrf1/select.htm So I made a #ifdef and hardcoded the first parameter to 1 for AIX. I'm not sure if this will have any side effects, especially for versions < 5.2 but I don't think so. The attached patch will do the change on the file openssl-0.9.7a/crypto/rand/rand_unix.c. Anders Liljegren tested it also on AIX 5.2 and found no problems.
