Comment 4 for bug 347651

I made a patch for fixing this bug, basically I added "/var/lib/boinc-client" to common-defs.h file.

So now when you fopen the path should make boinc point to the right file, could you (when the build will be successful) try this version?
boinc - 7.0.47+dfsg-0~1007 in my ppa
https://code.launchpad.net/~costamagnagianfranco/+archive/boinc

this version should fix this long stading bug
