Hi,  
Is anyone else having problems with curb \<[http://curb.rubyforge.org/](http://curb.rubyforge.org/)

$ ruby --version  
ruby 1.8.5 (2006-08-25) [i686-darwin8.8.2]  
$ gem query -n curb

\*\*\* LOCAL GEMS \*\*\*

curb (0.1.0)  
Ruby bindings for the libcurl(3) URL transfer library.  
$ irb -rubygems -rcurb  
dyld: NSLinkModule() error  
dyld: Symbol not found: \_curl\_easy\_escape  
Referenced from: /opt/local/lib/ruby/gems/1.8/gems/curb-0.1.0/lib/  
curb\_core.bundle  
Expected in: flat namespace  
$

(ruby, irb, and gem are all installed under /opt/local using MacPorts  
[http://www.macports.org/](http://www.macports.org/)).

I don’t know what this means (aside from the obvious that it’s a linkage  
problem). I found a number of references to similar problems, mostly I  
think with new(er?) versions of OSX, but nothing definitive. It’s a  
problem, so please do file a bug with Curb, but if anyone can shed any  
light on this issue I’d be most appreciative.

Cheers,

Just FYI, it looks like this has been fixed with curb version 0.1.2  
(now available as a gem). Thanks to Ross for the quick debugging and  
distribution of the fix.
