You can only install one copy of mysql5 (or any other port) with one  
installation of MacPorts.

If you want a second copy of mysql5 (which you would configure to run  
on a different port and with different data files), you can install a  
second copy of MacPorts. You would need to build this second copy  
yourself from source, to install into a path other than /opt/local. 

Note that you must also remember to use the configure flags to tell  
it to put applications, frameworks and most especially the tcl  
package in different locations so that it doesn't overwrite the ones  
your first MacPorts uses.

For example, to install into /opt/macports2:


./configure \
--prefix=$PREFIX \
--with-tclpackage=$PREFIX/Library/Tcl \
--with-applications-dir=$PREFIX/Applications \
--with-frameworks-dir=$PREFIX/Library/Frameworks \


sudo make install
