[xcrysden] xcrysden script for MacOS

[David Strubbe]

I am not sure what you mean. Isn't this checking whether external/lib
exists, as below:

if test -d $XCRYSDEN_TOPDIR/external/lib ; then
    if test -z "${LD_LIBRARY_PATH}"; then
LD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib"
    else
LD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib:$LD_LIBRARY_PATH"
    fi
    export LD_LIBRARY_PATH

    if test -z "${DYLD_LIBRARY_PATH}"; then
DYLD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib"
    else
DYLD_LIBRARY_PATH="$XCRYSDEN_TOPDIR/external/lib:$DYLD_LIBRARY_PATH"
    fi
    export DYLD_LIBRARY_PATH
fi

Since external/lib will always exist after building xcrysden,
DYLD_LIBRARY_PATH will always be set. No, I am not using anything from
external/lib, as you can see:

$ otool -L bin/xcrys
bin/xcrys:

current version 7.2.0)
