I was able to build the jpilot 0.99.6 on a gentoo amd64 system. It required setting the USE=-java on the command line. (It failed with the 64bit Blackdown java) The program works and I have been able to sync my palm with it. I recomend adding the ~amd flag. Reproducible: Always Steps to Reproduce: 1. 2. 3.
~amd64 added to keywords.
