When I run ./configure, usrp2 and gr-usrp2 doesn't get built. What should I do 
to get past this, since there is a check to see if the host OS is linux, and it 
aborts building the usrp2 and gr-usrp2 components.


checking whether host_os is linux*... no
configure: USRP2 currently requires Linux host OS, not found
Not building component usrp2.
Component gr-usrp passed configuration checks; building.
Component gr-usrp2 requires usrp2, which is not being built or specified via 
pre-installed files.
Not building component gr-usrp2.


*********************************************************************
The following components were skipped either because you asked not
to build them or they didn't pass configuration checks:

gcell
usrp2
gr-usrp2
gr-gcell
gr-audio-alsa
gr-audio-oss
gr-audio-windows
gr-comedi
gr-qtgui

These components will not be built.

Configured GNU Radio release v3.3.1git-30-g278b6db3 for build.
