(with this patch everything is good so far, the problem I think is the
-as-needed gcc flag active by default on ubuntu)
thanks

Hi David, I'm not sure about the following fix, but it should be correct.
The problem is that libboinc_api.so uses pthread but is not linked against it.
In the newer saucy development release /gcc-4.8 we are getting linking failures
because of it
an example of this issue
https://launchpad.net/ubuntu/+source/boinc-app-milkyway/0.18d-2/+build/4725147
ldd of the so file doesn't show the pthread library
and after my fix correctly shows the pthread and jpeg libraries.

So would be nice to have them addressed upstream too.
I'm already building the new boinc in debian/ubuntu, for checking again the fix,
but should be ok.
