Hi,
I encountered an error while attempting to install on my Ubuntu 9.04 machine. The error message and system info are below, but here is a summary of the problem:

The installation procedure called by source(REDACTED) is trying to download the file REDACTED/OpenMx_0.1.3-776.tar.gz, but this file does not exist. I manually downloaded REDACTED/OpenMx_0.1.3-776.tgz (note .tar.gz vs .tgz) and installed it with R CMD INSTALL. Everything appears to be fine, so I think all is needed is to fix the file name suffix.

-Ista

Errors and system info follow:
source('REDACTED')
