configure cannot find headers for libreadline

Hello everybody, Configure cannot find the headers for libreadline, although they are definately present. I tried setting the CPPFLAGS as in setenv CPPFLAGS -I/usr/locacal/gnu/include ./configure --prefix=/home/thef/chrisd/c++ but still configure does not find them. Does somebody know how to solve this problem? Note: I am on a unix where I am not allowd to set symlinks in system include dirs. (If this were allowed, I would probably not be posting anything here). Greetings, Chris Dams
