We should put in the installation structions a warning about the cantera 1.7 screwup

A quote from cantera mailing list in December 2007:
This line out of Makfile.in
rm -fR @ct_libdir@/*
cause some MINOR problems, if you type
./configure --prefix=/usr
because in configure the line
ct_libdir=${prefix}/lib
isn't that optimal.
If you didn't get it till now: I lost all user libraries!
