Gonzalo, thanks for the fast response. I downloaded the openssl-0.9.6g.tar.gz package, extracted it and ran "./configure --with-ssl=...openssl-0.9.6g". "make" still failed with the same error as before. I noticed some messages about not finding "engine.h", so I downloaded, extracted and pointed --with-ssl to "...openssl-engine-0.9.6g". "make" still failing with "common.h:318: #error OpenSSL library compiled without thread support". I will dig some more into what it takes to install the OpenSSL development package, although I suspect that the shared hosting environment I am using will seriously limit what I can do.

In order to compile, you need the OpenSSL development package. Hope that helps. Best regards.

I unpacked the tar file and ran "./configure" using --prefix to override the /usr/local/ install directory. I had one warning: "configure: WARNING: Openssl engine header not found". In terms of threading model, I got "configure: PTHREAD thread model detected". When I tried to run "make", I got "common.h:318: #error OpenSSL library compiled without thread support". Is there a way around this? I tried running "./configure" with --with-threads=ucontext/fork, but that gave a bunch of "OCSP_" undeclared variables and "Error 1".
