Jarred, after further analysis in regards to installing an earlier version of the Mechanize gem (i.e. 0.8.5), it has a couple of runtime dependencies:

hpricot >= 0.5.0, Note: This gem contains C Ruby native extensions.

hoe >= 1.8.2, Note: This gem contains pure Ruby code.

Thus, you'll still have issues installing earlier version of Mechanize gem like version 0.8.5 because if depends on a gem which has C Ruby native

extensions. I have been reading many threads on moving away from using C Ruby extensions to using FFI which allows any client that supports FFI to

easily connect to connect to native librarie(s). The benefit would be to allow one to do the following:

For example, using Nokogiri as an example:

a) build a Nokogiri interface and push the sources to github.com

b) push the Nokogiri library sources to MacPorts, Linux distros, and so

1) to MacPorts, Linux distros, and so

2) to github.com

BTW, this is very similar to what we need to do today to interact with MySQL, PostgreSQL, and SQLite3 relational databases from Ruby. However, Ruby FFI makes this process much easier. Lastly, you can read more about FFI here:

MacRuby's macgem doesn't support native gems (i.e. Nokogiri and Mechanize) at this time. Thus, the same problem will occur usually earlier versions of the gem.

Good luck,

Hey Guys

First off, Id like to say im loving macruby, its awesome.

The story starts after having some issues with webkit and cookie
sharing ive decided to roll back to good ole trusty mechanize.
and thus my journey with macgem begins.

terminate called without an active exception
Abort trap

The end.

I read somewhere that its not possible due to dependancies (nokogiri)
so i thought maybe i could roll back to the pure ruby version of it...
i think was 0.8.5 - 0.8.3 ??

$sudo macgem install mechanize --version 1.8.5
Password:
ERROR: could not find gem mechanize locally or in a repository

...

$ sudo macgem install --local mechanize-0.8.5.gem
terminate called without an active exception
Abort trap

I tried with 1.8.3, no cigar...
little help?
