I lucked out. The timer functions you're using are all standard under OpenBSD without loading any libraries, so I just removed the -lrt and it compiles and seems to work. I just got the dongle in the mail today so I haven't actually seen it work yet due to other screwups, but rtl_test and everything else seem to work. It's a NooElec R820T, serial # 13 according to the eeprom. Came from somebody selling through Amazon. $19.95 with a remote and a magmount antenna. Seems to have a protection diode. Strange (MC?) antenna connector, gotta extend that out of the basement somehow. Seems well made.
Found 1 device(s):

I've got more downloading to do before I can actually hear anything on it.
