Problems compiling Ruby 1.8 CVS

[Austin Ziegler]

I checked out the CVS HEAD yesterday, transferred it to my web host (where I
have access to gcc), converted the files from DOS to Unix format, ran
autoconf and configure with:

./configure --prefix=$HOME

I ran make, and got:

ossl_cipher.c: In function `ossl_cipher_new':
ossl_cipher.c:57: void value not ignored as it ought to be

I don't know what version of OpenSSL is necessarily being provided by the
web host, but I have compiled and installed 0.9.7-latest into $HOME/openssl.

I have also tried adding $HOME/openssl to the search path.

1. Why is this failing?
2. Do I need to tell Ruby where to find my OpenSSL installation?
How?
