Problems installing Ruby with RVM on OSX Yosemite 10.10.2
13 Mar 2015I tried to install Ruby 1.9.3 using RVM but it had problems auto detecting the correct compiler.
TLDR;
Error
$: rvm install 1.9.3
...
couldn't understand kern.osversion `14.1.0'
ld: dylib ./libruby.1.9.1.dylib missing LC_ID_DYLIB load command file './libruby.1.9.1.dylib' for architecture x86_64
collect2: ld returned 1 exit status
make[1]: *** [.ext/x86_64-darwin14.1.0/enc/encdb.bundle] Error 1
make: *** [enc] Error 2
+__rvm_make:0> return 2
There has been an error while running make. Halting the installation.
Solution
$: brew install gcc48
$: CC=/usr/local/Cellar/gcc48/4.8.4/bin/gcc-4.8 rvm install 1.9.3
Background information
$: rvm install 1.9.3

Looking at the error log showed that it might be using an incompatible version of gcc.
