[Zope] pcgi, make install: root necessary?

[Florian Konnertz]

I installed zope as user and continued to install pcgi.
When I do make install, i get:
flo@grooveway:/usr/local/dc/zope/pcgi$ make install
./install-sh -c                                                  -m 755

            pcgi-wrapper /usr/local/bin/pcgi-wrapper2.0a5
cp: cannot create regular file `/usr/local/bin/#inst.929#': Permission 
denied
chmod: getting attributes of `/usr/local/bin/#inst.929#': No such file 
or directory
rm: cannot unlink `/usr/local/bin/pcgi-wrapper2.0a5': Permission denied
mv: cannot stat `/usr/local/bin/#inst.929#': No such file or directory
cp pcgi-wrapper /usr/local/bin
cp: cannot create regular file `/usr/local/bin/pcgi-wrapper': Permission 
denied
make: *** [bininstall] Error 1

Is it necessary to do  this as root or is it possible to change the 
permissions in
/usr/local/bin ?  Isn't this dangerous to allow a user to write here?

greetings,
Florian
