[Rubycocoa-talk] Tidy + RubyCocoa: Error triggered in dl/import.rb

[Avram L. <aj...@gm...>]

I'm working on a RubyCocoa front-end for a Ruby library I wrote to
access a certain web forum. The library uses the Tidy gem to normalize
the messy HTML it gets from the web server before using REXML to parse
out the needed content. This works fine for me when I'm using plain
old Ruby, but when I call:

Tidy.path=LOCAL_TIDY_LIB_PATH

from my RubyCocoa app, I get a RuntimeError (trace below). As the
trace shows, the error is thrown when dl/import.rb tries to load the
local HTMLTidy library (/usr/lib/libtidy.dylib).

My gut instinct here is that this a limitation of RubyCocoa -- I can't
use dynamic loading. Is that the case? If so, is there a way to work
around it? I've looked at the Tidy gem project documentation and the
RubyCocoa documentation, and I don't see anything related to this.

Thanks in advance for any and all advice,

Avram Lyon
