Hmm,

Now try to build system, very weird:

CPU0 states:  5.4% user,  0.0% nice, 94.6% system,  0.0% interrupt,  0.0% idle
CPU1 states:  7.8% user,  0.0% nice, 92.2% system,  0.0% interrupt,  0.0% idle
Memory: 452M Act, 253M Inact, 1060K Wired, 9108K Exec, 582M File, 67M Free
Swap: 4883M Total, 4883M Free

  PID USERNAME PRI NICE   SIZE   RES STATE      TIME   WCPU    CPU COMMAND
  22863 dina      64    0  5868K   14M RUN/0     90:28 99.02% 99.02% cc1
  22718 dina      64    0  9900K   34M CPU/1     89:37 99.02% 99.02% cc1

Build process stuck at this point:
