I’m trying to run ruby extconf.rb in ext/openssl, and I get the  
following:

=== OpenSSL for Ruby configurator ===  
=== Checking for system dependent stuff… ===  
checking for t\_open() in -lnsl… no  
checking for socket() in -lsocket… no  
checking for unistd.h… yes  
checking for sys/time.h… yes  
checking for assert.h… yes  
=== Checking for required stuff… ===  
checking for openssl/ssl.h… no  
=== Checking for required stuff failed. ===  
Makefile wasn’t created. Fix the errors above.

I’m using Ubuntu 6.10… can anyone tell me what I can do to fix the  
problems? I have openssl installed via ‘apt-get install openssl’

I don’t even know what the first two are talking about at all (the  
t\_open and socket())

Answered my own question, at least  
sudo apt-get install libssl-dev
