As a check about the ownership/permissions on the port, you might do a "chmod 4755 /usr/local/bin/xastir" as root to set the SUID bit in the executable. If Xastir works for you then, it's an ownership/group/permissions issue with that port.
We need to set that bit on Linux in order to open an AX.25 networking port. That's its main use.
