No - it implies that install.pl is not smart enough to edit the Makefile 
completely.  Maybe I should work on that

BUT - why are you compiling it yourself?  We supply a 64-bit binary done 
with the Intel compiler that outperforms the gnu compiler by a lot (e.g. 
40% in some measurements).

The -axWPT is needed for Intel and should be deleted in the Makefile for 
gnu compiler.
