I don't think so. You either have to use an older mkgmap version or upgrade your
OS X installation to Lion or newer. You can check in the commit logs when mkgmap
dropped java1.6 support and use that mkgmap version. I know that r2960 can run
on java1.6

I upgraded from SL to Mavericks recently in order to get java7 and keep up with
mkgmap.
