----------------------------------------
Hi, 

I'm trying to build Ruby from sources.

What I tried:

1) Build from git using git clone, autoconf, ./configure
2) Build with RVM versions 2.2.1, 2.2-head, 2.1.5, ruby-head

All have failed when reaching the "./configure" phase.
It seems that all memory is getting eat up and the system hangs unless a quick "Ctrl + C" is pressed to stop the process.

Notes:

* I had ruby installed and working until trying to re-build
* I had a system restore which left most of /home/ with wrong permissions (was taken care of but maybe Ruby's configure needs some files with +x which don't have them right now?)
* Other programs which relays on "./configure" scripts work and build without issues.
