The system is 8.2-RELEASE GENERIC amd64 on Intel quad core. I do not understand how pth threads are managed. 1. From ports I have installed fpc-pthreads-2.6.0 libpthread-stubs-0.3_3 pth-2.0.7 2. I am totally ignorant of what is installed by the kernel or of how to check whether there are any conflicts in the system or the ports. 3. I want to install Jabber which seems to require pth-hard 4. The greatest concerns seem to be around Xorg with kde4 installed 5. Fundamentally I am concerned that something about thread management on this system is fouled up. For example kde4, following a recent upgrade,has taken to not loading. Would someone be willing to enlighten me a little? 6. To show the my concerns are not without some foundation among the multiple error messages given when kde4 fails to load there is the snippet shown below.
