 I've just noticed the same issue with 'mplayer'.  As with 'uic', it hangs
 trying to "mmap()" the file descriptor previously obtained by opening
 ""/usr/pkg/lib/libGL.so.1".
 
 [...]
    105      1 mplayer  open("/usr/pkg/lib/libGL.so.1", 0, 0xbfb53350) = 3
    105      1 mplayer  __fstat50(0x3, 0xbfb53350)  = 0
    105      1 mplayer  mmap(0, 0x1000, 0x1, 0x1, 0x3, 0, 0, 0) = 0xb125b000
    105      1 mplayer  munmap(0xb125b000, 0x1000)  = 0
    105      1 mplayer  mmap(0, 0x67000, 0x5, 0x2, 0x3, 0, 0, 0) = 0xb11f5000
    105      1 mplayer  mmap(0xb124e000, 0xe000, 0x7, 0x12, 0x3, 0, 0x58000, 0) Err#13 EACCES
    105      1 mplayer  munmap(0xb11f5000, 0x67000) = 0
 [hangs here]
 
 Again, this only occurs with modular Xorg.
