#3 Make error libgsl referenced before input

[Michael Tsikerdekis]

I've tried building the latest version and there was an issue with linking. Mainly with finding elements of libgsl.

I made the following change in the make file and it worked.
@$(GCC) $+ $(CFLAGS) -o $@

Basically switched $+ so that the flags will come after it otherwise you get the following errors:
Linking lanet...

I am using ubuntu 13.04
