Hi. I'm sure this is an easy problem for experienced linux users and your help is MOST appreciated. I have configured a program called CLHEP and all tests pass. However my next directive is to type "make install," and here the problem arises. For some reason there is a permission issue on my computer. Can anyone please solve this problem????? The following is direct text of where the problem begins.
 
make[1]: Leaving directory `/home/winn/CLHEP/StdHep/include'
for dir in config Utilities Evaluator GenericFunctions Matrix Vector Random RandomObjects Geometry Units HepPDT HepMC HepMC/include StdHep StdHep/include ; do cd $dir ; make install prefix="/usr/local" MKDIR="mkdir -p" ; cd /home/winn/CLHEP ; done
make[1]: Entering directory `/home/winn/CLHEP/config'
test -d /usr/local/include/CLHEP/config || mkdir -p /usr/local/include/CLHEP/config
mkdir: cannot create directory `/usr/local/include/CLHEP': Permission denied

Thank you so much!
