Confusing error message in configure

[denysvitali]

Took me a while to figure out what my problem was, but basically the libupnp error message is badly copy & pasted from libfuse, causing some confusion if you don't have libupnp installed :)

avmount/configure.ac

Line 262 in ccf358f

AC_MSG_ERROR('Unable to find libfuse. Please make sure library and header files are installed.'))
