When building bitcoind from source, how to specify stable build? I managed to build bitcoind on arch linux after downloading the source from github, but after running bitcoind getinfo command, I am told:


  "errors" : "This is a pre-release test build - use at your own risk -
  do not use for mining or merchant applications"


How can I remove that message and use a stable build, instead of the pre-release one I downloaded?

I assume I have to do something with the information found here: https://github.com/bitcoin/bitcoin/tags
If you got the source via git, you can checkout on the latest stable release tag, currently v0.8.1 using the git command git checkout v0.8.1.

When you did not setup git, you can simply download the source from that tag version from the webpage you suggested using either the .zip or .tar.gz link underneath the tag name. vX.X.X releases are stable ones, while the vX.X.XrcX releases are release candidates, meaning that they can still contain a few bugs.
