From Jeffrey Morlan: pst_parse_block returns null upon finding a property of unrecognized type. Many PSTs contain messages with these - it should just ignore the property, not the whole message. Again, this causes missing emails.

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
