Hello, I am new in jogl and 3d programing in java and I was trying to get jogl to work with my gentoo in 64 bit mode. There are no precompiled bins so I was trying to compile them my self but no luck 
Im using sun-jdk1.5.0 and have also tried blackdown 1.4.2 Here is the error output
java.generate:
[echo] Generating GL interface class
^[OH [echo] Generating GL implementation class
