OpenBSC + USRP

Hi list, I'm trying to install the OpenBSC and made it work with a USRP N210 device. I'm having trouble installing the OsmoBTS (following this tutorial: http://openbsc.osmocom.org/trac/wiki/network_from_scratch). However, if I understood correctly, this tutorial is to use the with a UmTx device, right? Is there a tutorial to configure all the environment for a USRP device ? Btw, I having the following compile error when compiling the OsmoBTS with the --with-trx option: In file included from sysmobts_test.c:22:0: ../../src/osmo-bts-sysmo/femtobts.h:7:42: fatal error: sysmocom/femtobts/superfemto.h: No such file or directory Best Regards,
