In general it shouldn't need to be. The only environment variable you need 
to set is PATH. In Mercury 0.11, setting the MERCURY_MATH_LIB environemnt 
variable allows you to override the way in which the Mercury linker will 
link in the math library. The default is determined when `configure' 
is run.

What happens when you do what I originally suggested? 


...Same thing as before: 
/usr/bin/ld: cannot find -lc 
collect2: ld returned 1 exit status 

....maybe I'd better change linux distribution....
