[Click] errors compiling click simplepackage from cvs

Hi Guido,

I can't replicate this problem with my setup.  I build Click and install it in 
the directory /usr/local/click, and then configure the etc/samplepackage with 
--prefix=/usr/local/click .  What configure args, if any, did you supply to 
samplepackage?  Did you "make install" Click first, before configuring 
samplepackage?

Eddie
