Ettus e110 - newbie problem

I tried to update UHD on the e110 to the latest version from the Ettus
site and now when I type uhd_usrp_probe I get the error;

linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500;
UHD_003.004.002-171-g7c8fef85

– Opening device node /dev/usrp_e0…
Error: EnvironmentError: IOError: Could not find path for image:
usrp_e110_fpga.bin

My path (echo $PATH) is;
/usr/local/bin:/usr/bin:/bin:/usr/share/uhd:/usr/share/uhd/images:/usr/local/sbin:/usr/sbin:/sbin

When I run uhd_usrp_probe from the /usr/share/uhd/images directory it
works OK. SO obviously some sort of path issue but I cannot suss what
the problem is.

Can anyone help?
