make for qpid 0.12 fails in a number of places.
See the following mailing list thread for more details:
I believe this relates to changes made to the linker behaviour for recent gcc versions so I suspect that this issue isn't limited to Linux Mint 12. See http://fedoraproject.org/wiki/UnderstandingDSOLinkChange (this is a Fedora page and I'm using Mint but the symptoms seem identical).
I've put together a patch for this which I'll attach when the Jira gets created.
