Hi Germán,
Welcome :-) Could you please subscribe to the list so that I don't have to moderate each of your messages? Thanks!
If you use Ubuntu maybe you could try using the pre-compiled packages instead of compiling your own? Compiling the compiler needs a bit less than 3Gb virtual memory. I guess you got beaten by the OOM killer :-)
You can find detailed instructions at:
http://apt.liberty-eiffel.org — The packages are built for Debian but they should work on derivatives, please tell us if they don't.
Best regards,
Cyril
