$FOObar means variable $FOObar. Capisce?

Hi,
I have a problem with bash vars. For my KDE copileing stuff i have made some
files wich contain the "configure" command so that i can easily alter it and
that i can remember wich options i used. E.g. there is a file "conf_kdelibs"
the file contais that line:
./confugure --prefix=/opt/kde --
