yeah so if you don't use --prefix=/usr
then your header files are going somewhere
else right?
in this case you would need to specify with
--with-headers

In any case I try to keep things simple
by defining --prefix=/usr.

as for the last question, no.
probably more of a pain if anything
i.g. given the app/lib you might need
to adjust the Makefile to point
in the right direction. for libc
--with-headers seems to be it, but if you use
--with-headers=/opt/
then libc shoots right to there for everything
(could be wrong though)instead of looking at
/opt/
and
/usr/include/
to do it's building.
