rvm: Syntax error when I'm trying to install on a machine running SME Server

Question

I'm trying to set up a Rails server to run an app that I just wrote on a box running SME Server 7.4.

I've installed curl, zlib, and readline, but when I run the rvm script, I get this output:

$ bash < <(curl -sk https://rvm.beginrescueend.com/install/rvm)
Cloning into rvm...
remote: Counting objects: 4757, done.
remote: Compressing objects: 100% (2427/2427), done.
remote: Total 4757 (delta 3082), reused 3183 (delta 1672)

Resolving deltas: 100% (3082/3082), done.
bash: line 298: syntax error near unexpected token `"--trace"'

Any idea what could be causing this?

Answer 1

I figured it out.

Turns out that I was running an super-old version of bash. Installing 4.2 fixed this, and RVM installed perfectly.

For the record, RVM needs bash v3.2 or better.
