Got errors compiling the extensions

[leoc]

I got some errors as I added rfusefs to my projects Gemfile. Rfusefs depends on rfuse-ng.

Installing rfuse-ng (0.5.3) with native extensions

An error occured while installing rfuse-ng (0.5.3), and Bundler cannot continue.
Make sure that `gem install rfuse-ng -v '0.5.3'` succeeds before bundling.

Then I forked and the first thing I did was to switch the whole thing to a setting that´s bundler specific. It was kind of mixed with a Jeweler Rakefile.

When I did a rake install everthing installed fine.

I don´t know.

Maybe the previous bundler installations changed the C standard to C90 and we have to add something like

with_cflags("-std=c99 #{$CFLAGS}") do
  create_makefile("rfuse-ng")
end

For some reason I get another error with Ruby 1.9.2, though I thought it was forked and modified for Ruby 1.9.2 compatibility.

Here again, when I do rake install within an RVM Ruby 1.9.2 environment everthing installs just fine.
