Hi Tiago! We are sorry that the PostgreSQL gem is not yet fully installable via macgem. The one we managed to install was ruby-pg 0.9.0 ( http://bitbucket.org/ged/ruby-pg/downloads). However, the gem in itself has an extconf.rb file with a syntax that is not yet supported in MacRuby and probably won't be soon enough. To install and use ruby-pg, you'll need to do the following: - Download ruby-pg 0.9.0 from http://bitbucket.org/ged/ruby-pg/downloads - Extract wherever you want, let's say in /tmp/ruby-pg for example - Go in the extracted ruby-pg directory, and apply the patch ( https://gist.github.com/00be9e82ed4fd548c29d ) by doing: patch -p0 < /path/to/extconf.rb - cd into the "ext" directory, and run the following commands: $> macruby extconf.rb # potentially add --with-pg-config if you need $> make $> sudo make install You will have to make sure that your local installation of PostgreSQL is compiled for both i386 and x86_64 bits, MacRuby requires it. Once you have issued the latest command, the extension "pg_ext" will be installed (without needing gems). You can either rename pg_ext to pg, or create a pg.rb file that requires pg_ext (which is exactly what the gem does when installed, however installing ruby-pg has proven to less than straightforward [even with ruby19], so it's easier to do it this way ;-)). Hope this helps, good luck with that! -- Thibault Martin-Lagardette On Tue, May 4, 2010 at 14:06, Tiago Ribeiro <tiagor@mac.com> wrote:

Amazing.

I'm mostly amazed by this specific breakthrough:

"MacRuby 0.6 provides support for C extensions written for the original implementation of ruby. We were able to successfully use the Nokogiri, SQLite3 and PostgreSQL extensions from MacRuby."

How did you manage to install the PostgreSQL extension with macgem? Any special setup?

Thanks a lot

Hi,

After 3 months of development since the last release, MacRuby 0.6 is now available. Get it here while it's still hot!

MacRuby is an implementation of Ruby 1.9 directly on top of Mac OS X core technologies such as the Objective-C runtime and garbage collector, the LLVM compiler infrastructure and the Foundation and ICU frameworks. It is the goal of MacRuby to enable the creation of full-fledged Mac OS X applications which do not sacrifice performance in order to enjoy the benefits of using Ruby.

You can learn more about MacRuby, and download a binary installer, from the website:

http://macruby.org

Or about this release more specifically, on our blog:

Enjoy,

Laurent
