    What I always do is just go into the directory I'm patching and use `patch
    -p1`. That way it doesn't care at all what the directory prefix is for
    either the original or patched trees. Works all the time (unless whoever
    made the patch used some weird method to create the patch...)

    For instance, my script to extract a guaranteed clean version of the
    latest kernel tree from my archive of linux-2.0.tar.gz and patch-2.0.*.gz:

    -----------
    #!/bin/sh
    echo -n Cleaning...
    rm -rf `/bin/ls -l linux | awk '{print $11}'` linux
    echo
    echo -n Extracting...
    tar -xzf linux-2.0.tar.gz
    echo
    cd linux
    echo -n Patching
    for n in ../patch-2.0.?.gz ../patch-2.0.??.gz;do
    LATEST=`echo $n | sed 's/\.\.\/patch-\(2\.0\.[0-9]*\)\.gz/\1/'`
    zcat $n | patch -p1 -s
    echo -n .
    done
    echo
    echo -n Wiping .orig files...
    find . -name '*.orig' -exec rm {} \;
    echo
    cd ..
    echo Latest version is $LATEST
    mv linux linux-$LATEST
    ln -s linux-$LATEST linux
    ----------

    Note that this does no error checking. This is because all the linux
    patches are perfect (know a guy who patched all they way from 1.3.1[0-9]
    to somewhere in pre-2.0 without a problem) ;-)

    TTYL,
