Node throws error (Unexpected number) on compilation

[rricard]

Hi !
It's been a few hours I'm fighting with the r.js compilation (note : that works on heroku, but other errors are thrown anyway !).
Every time I'm trying to compile ... I get this (with --trace argument) :

** Invoke assets:precompile (first_time)
** Invoke requirejs:precompile:external (first_time)
** Invoke requirejs:test_node (first_time)
** Execute requirejs:test_node

Asset compilation with node failed.

I tried with three different node versions (0.6.21, 0.8.4 and 0.9.0). I don't think it comes from my code (for the moment, it's just as simple as the samples) but from somewhere else I don't know (maybe node considering that I'm using the n version manager).
I tried to use the r.js command directly but it does not play nice with the rails directory structure.
If you have any idea or help to give me : first, to debug this (I'm ok with pure ruby or pure node debugging but this ...) and if you have more time, to locate and patch with me (if it's a bug) this error.

Anyway, thank you for the awesome plugin !
I'll continue to investigate ... !

EDIT : I think I found it by following the node stack trace ! I added in the rake task in your gem a line which is supposed to print the temporary rjs driver :

print `cat #{requirejs.config.driver_path}`

And ... surprise ! the path to the driver is incomplete ! I had a space in one of my parent directories that wasn't escaped well ! I'll give you a patch soon !
