opa on 32 bit (x86) installs 64bit mongodb (x86_64)

[vagn]

opa on 32bit installs downloads and tries to use 64 bit mongodb, which of course won't run. Opa needs to do achiteceture test and download correct mongodb archive.

I'm using the workaround below, basically sticking my own mongodb download in place and fooling opa into accepting it. Ugly, but it works. Updates to these scripts will be posted at

http://agawamtech.com/blog/2013/03/opa-from-source-on-ubuntu-12-04-lts/.

if anyone is interested.
