Installation problem of usrp package in fedora 15

I have installed libusb in Fedora 15 (it is installed in /lib64)

ls /lib64/libusb*
lrwxrwxrwx. 1 root root 19 Oct 5 16:17 /lib64/libusb-0.1.so.4 ->
libusb-0.1.so.4.4.4
-rwxr-xr-x. 1 root root 20376 Jun 22 04:09 /lib64/libusb-0.1.so.4.4.4
-rw-r–r--. 1 root root 85498 Feb 8 2011 /lib64/libusb-1.0.a
lrwxrwxrwx. 1 root root 19 Oct 7 20:04 /lib64/libusb-1.0.so ->
libusb-1.0.so.0.0.0
lrwxrwxrwx. 1 root root 19 May 13 15:42 /lib64/libusb-1.0.so.0 ->
libusb-1.0.so.0.0.0
-rwxr-xr-x. 1 root root 56280 Feb 8 2011 /lib64/libusb-1.0.so.0.0.0
-rw-r–r--. 1 root root 19362 Jun 22 04:09 /lib64/libusb.a
lrwxrwxrwx. 1 root root 19 Oct 5 17:01 /lib64/libusb.so ->
libusb-0.1.so.4.4.4

I have also added /lib64 on my LD_LIBRARY PATH :

export LD_LIBRARY_PATH=/usr/local/lib64:/lib64:$LD_LIBRARY_PATH

When I run
configure --enable-usrp
on the latest master branch
I get the following error:


checking for sigaction… (cached) yes

what is going wrong?

Thanks
