If you get stuck installing GnuPG.pm on FreeBSD because the 'make test' hangs on generating the key, here's what to do:

* As root:
# vmstat -i

make note of the irqs that have nonzero rates
and are not clk* or rtc*

Issue the command:
# rndcontrol -s n

for 2 or 3 of these irqs where "n" is the irq number

What you are doing here is telling the OS to use these devices to coll
+ect randomness from.

For a longer term solution you can add these irqs to your rc.conf file so they are saved through reboot:

 
rand_irqs={some good irq numbers here}
