When compiling on a Fedora Core 3 w/o openssl-devel rpm
installed the configure script reports a "too old"
error even if the
openssl version is correct.
This is caused by the configure script not checking for
the existence of the header file openssl/opensslv.h
before using it in a compile test.
Attached is a little patch against configure.ac in
0.6.2 to fix that.
