that's good!

You did not send any actual error message here, so it's difficult to tell 
where exactly your install failed. But gfortran is preferred over f77 etc. 
and should in fact be automatically selected (without the '--fcompiler=gfortran'), 
it is apparently also found in the right place. 
Could you send us the last lines of output with the error itself, or possibly  
everything following a line starting with "Traceback:.." ; 
and also the output of `gfortran -v`?
