 Rebooting to clear out the stuck 'uic' processes then executing the
 same command line under 'ktruss' shows:

 [stuck here]
 
 The EACCESS result from "mmap()" suggests perhaps a PAX MPROTECT issue?
 
 Setting:
 
   paxctl +m ${WRKOBJDIR}/x11/qt3-tools/work/qt-x11-free-3.3.8/bin/uic
 
 Allowed it to complete.  Again, this is only needed when using modular
 Xorg.
 
 "qt4-tools" also builds a 'uic' tool but it does not exhibit any problem
 with modular Xorg.
