And you're never going to be able to solve that problem.

It's really not that hard. I use the exact same .bashrc and .profile on
every single platform I have a login on, and that's dozen's of different
flavors of Linux and UNIX.
What I've taken to doing is having a "generic" .bashrc that sets things
like PATH, MANPATH, et. al. based on
case $HOSTTYPE in
foo*)
...
;;
bar*)
...
;;
baz2.7)
...
;;
baz*)
...
;;
esac
and then I have a section at the end of my .bashrc that does:
short_hostname=`uname -n | cut -d. -f 1`
# Since we're not consistent about case, force lower case
domain_name=`egrep 'domain|search' /etc/resolv.conf \
| sed -n '$p' | awk '{ print $2 }' | tr '[:upper:]' '[:lower:]'`
#
# Try the FQDN one, first.
#
if test -f $HOME/.setup/${short_hostname}.${domain_name}.bashrc || \
test -L $HOME/.setup/${short_hostname}.${domain_name}.bashrc ; then
. $HOME/.setup/${short_hostname}.${domain_name}.bashrc
elif test -f $HOME/.setup/${short_hostname}.bashrc || \
test -L $HOME/.setup/${short_hostname}.bashrc ; then
. $HOME/.setup/${short_hostname}.bashrc
else
# don't do anything!
:
fi
In other words, load a host-specific .bashrc if it exists, from my
personal $HOME/.setup directory. I also have a section that loads an
OS-specific .bashrc, so that I only need a host-specific .bashrc for
really weird hosts -- most of things can be taken care of by the main
.bashrc, with a little tweaking in the platform-specific .bashrc.

BTW, you're aware that it's a bad idea to produce any output (your echo)
or modify any terminal settings in your .bashrc, right? The proper place
for those things is .profile.
