the jpilot-0.99.2.ebuild fails due to a failed ./configure in the syncmal plugin build. the syncmal ./configure fails because it is looking for /usr/include/libpisock/pi-config.h, which no longer exists in the version of pilot-link installed via the pilot-link-0.10.99.ebuild.
the jpilot-syncmal version was an old one. I have updated the -r1 ebuild to download the 0.71 release of the syncmal plugin and this fixes the problem. Thanks for catching this.
