can't compile jdk on machine with limited ram

Hope this is the right place for this question.  

I'm trying to compile the sun jdk14 port but I'm getting out of memory
errors.  This is an old machine with only 64mb of ram but I have a
whole 10gb drive as my swap space.  When I get this error, the process
size in memory is only around 100mb (it goes up to 120mb at other times
and is fine).  I've tried killing every process that is not essential
to free up mem but it still dies.  So my question is, has anyone
compiled the jdk on a machine with 64mb or less? and are there options
I can set to reduce the memory needed while compiling?  If it is
important, I'm using FreeBSD 5.3-RELEASE. Thanks.

This is the error message:
