download and untar version 0.4.0b, cd into the wavemon directory
it wouldn't compile for me til I edited the wavemon.c file:
go to line 173, change
CODE
exit();
to
CODE
exit(0);
then run
CODE
./configure && make
(you'll see some warnings, ignore them)
then cp the wavemon binary to /usr/bin/ or wherever you like (or run
it right there with ./wavemon )
wavemon is groovy
