Yes, there are troubles with signal.c

signal.c: In function ‘sigsegv’:
signal.c:622:2: error: implicit declaration of function ‘write’
[-Werror=implicit-function-declaration]
signal.c: In function ‘trap_handler’:
signal.c:812:17: warning: variable ‘proc’ set but not used
[-Wunused-but-set-variable]
cc1: some warnings being treated as errors
make: *** [signal.o] Error 1

This is on Ubuntu 12.04 x86_64.

Furthermore rvm binaries are not yet available for that platform and the
checksum for rvm is missing.

$ rvm --version

rvm 1.20.9 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal
Papis <mpapis@gmail.com> [https://rvm.io/]

$ rvm install ruby-1.9.3-p426
...
There is no checksum for
'http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p426.tar.bz2' or
'ruby-1.9.3-p426.tar.bz2', it's not possible to validate it.

So I downloaded the file manually, checked that the MD5 and the SHA256
matched and then run

$ rvm install ruby-1.9.3-p426 --verify-downloads 1

Then got the error.
