# An uberhack for Mac OS X 10.5: download-using-manifests uses Perl,
# and Perl links against Darwin's libutil.dylib (in /usr/lib), but
# when running "make check", the libtool wrapper script around the Nix
# binaries sets DYLD_LIBRARY_PATH so that Perl finds Nix's (completely
# different) libutil --- so it barfs.  So generate a shell wrapper
# around download-using-manifests that clears DYLD_LIBRARY_PATH.
