| | |   18231 [dblack candl] What happened to ' more' ?

^ Newbie. Sinking fast. Please help.
18188 [matt greenvi] I bought Programming Ruby a number of months back and finally have an opportunity to try out Ruby. However, I can't get it to build. Actually, that's not quite accurate. It builds fine. It won't pass 'make test'.

| 18240 [matt greenvi] So, what's the recommended course of action for me to take? I've been tinkering and trying to get it to build for about 20 hours now... (That's excluding sleeping time.) I'm no closer than when I started. I'd really like to use ruby for this project, but it's already taken me 10 times longer to try to just build it than it would have to have written this in perl. I was allocating extra time since I don't know ruby yet, but this is ridiculous! ;)
| 18252 [Dave Pragmat] OK - the situation is that you have a test that's failing. We don't
| 18264 [matt greenvi] $ make test
| 18266 [matt greenvi] OK, tried to compile it on fbsd 4.3 from source (not ports) and it worked fine. So, it's not inherently FreeBSD that has issues. It may even be just this one 3.3 machine.
+ 18195 [neumann s-di] Ruby is included in FreeBSD's ports collection. Thus, you don't have to build it yourself.
  18196 [matt greenvi] I'm aware that it's in the ports collection. However, FreeBSD isn't the platform on which I'm most proficient. It just happens to be what the machine I'm on is running. I'm not root, so AFAIK I can't install anything from the ports tree. That's why I'm building by hand. I'm not sure that I'd trust the patches to 1.4.0 (what's in th ports tree on here) applied against 1.6.4. But I'll take a look anyway. Not being familiar with Ruby, I doubt anything in there will jump out at me and say "Look! Apply me and life will be good!"... ;)
