i was getting the same error message but
i used those modified scripts and got a lot further.
my redhat 7.3 system has glibc-2.2 installed
and the shell script stopped because it wants glibc-2.3
but i ran "make install" manually and it recompiled everything ok.
it is working rather well so far - smooth and fast!
more notes later if i see any glitches.
