Ping?

I believe I got around this bug by using a different version of papi.

[citibeth]

I just checked... yes, I compiled successfully with papi 5.6

I am interested as a packager of blitz for openSUSE. It isn't possible in this case to compile with a lower version of papi since the distro (Tumbleweed) has already moved on to papi 6. We will have to drop the package from the distro instead.
