XTHash fails to find libcrypto in Linux / Altitude only on Win32?

> I deployed Altitude in CentOS and it produced a debug log, which I've attached below. Altitude needs SHA hashes and asks Xtreams for them. Works in Mac. Seems to fail in CentOS.
>
> XTHash makes an OS choice. If it's not Win32, then it uses XTLibCryptoHash. That works on Mac. On Linux it throws #externalCallFailed.
>
> So, the Linux class - XTLibCrytpoHash - fails on Linux, but works on Mac. The Mac class - XTHMAC - isn't used at all.
>
> Suspecting I may be wrong, and feeling limited by looking only at a command line, I downloaded Virtualbox, loaded CentOS 5.3, Squeak, and Altitude.
>
> I updated to the latest Squeak build - #12145 and ran the tests for Xtreams-XtrasTests. That package contains XTHMACTest and XTHashTest. All six tests failed.
>
> They try to find libcrypto, which seems ready to be found at:
>
> /usr/lib/.libcrypto.so.1.0.0.hmac
> /usr/lib/.libcrypto.so.10.hmac
> /usr/lib/libcrypto.so.1.0.0
> /usr/lib/libcypto.so.10
>
>
> I'm going to venture to say that people who use Xtreams in Squeak are more likely to deploy it on Win32 than Linux. Does anybody use Xtreams in Squeak and deploy on Linux?
