Strawberry Perl ships with both ssl and crypto libraries, named libssl32.a and libcrypt32.a. I tried copying the libraries to, respectively, libssl.a and libcrypto.a. The warnings about missing libraries went away, but the complaints about the unresolved references didn't. The RAND_* functions appear in openssl/rand.h, which ships with Strawberry, so the functions should be in there somewhere, right? I'm wondering if this is a configuration problem either with Strawberry Perl (v. 5.8.9.3) or (much less likely, I assume) with the CPAN module.
