To have the tar unpacking of the test directories use the stored user/group info would have to have the tar run as root.  Otherwise it would change all ownership to fink-bld which I believe would be fine.

It might be worth verifying whether just “tar” is being used, which would be Fink’s GNU tar, or “/usr/bin/tar”, which is Apple’s BSD tar.

It’s probably quicker to test as fink-bld because the tests fail promptly, possibly for different reasons than when building as root.

fink-bld is set up as an unprivileged user with no home directory or shell. 

$ id -P fink-bld
fink-bld:*:600:600::0:0:Fink Build System:/var/empty:/usr/bin/false

The problematic tests may expect one of those.
