Error bulding Java jdk15 - FAQ?

[Norberto Meijome]

Hi there,
I'm having trouble building jdk15 under  FreeBSD 6.1-PRERELEASE, with world, kernel and ports up to date. It
dies with

i have linux.ko loaded and 
linprocfs on /usr/compat/linux/proc (linprocfs, local)

mounted. I also have these 2 ports installed already:
javavmwrapper-2.0_6 Wrapper script for various Java Virtual Machines
linux-sun-jdk-1.4.2.10 Sun Java Development Kit 1.4 for Linux

Any idea?

Thanks!!
