From Jeffrey Morlan: If a readpst child process fails with a nonzero status code for whatever reason (killed, segfault, out-of-memory, ...) the parent process will continue and likely end up exiting with status 0, tricking the caller into thinking readpst was successful when it was not.

Starting with an unpacked tarball, try this:

    ./configure
    make
    su
    make install


Starting with a mercurial working directory, try this:

    make -f *cvs
    (cd xml; make; make distclean)
    make distcheck
