1) Make sure anope-1.7.17.tar.gz is downloaded correctly
2) Make sure anope-1.7.17.tar.gz extracted correctly - no errors during un-tar'ing.
3) Run ./Config in the anope-1.7.17 directory, and check for any errors
4) Run make and make install
I've tried it using a fresh tarball of 1.7.17 here and it worked fine, so there must be something going wrong on your system somewhere - probably in Config/configure.
