Port Upgrade Error

[Ted Kord]

Hi

I just tried to upgrade a port; CGAL but I get this error:

Error: Target org.macports.activate returned: Image error:
/opt/local/include/CGAL/Algebraic_kernel_d_1_RS_Gmpq.h already exists and
does not belong to a registered port.  Unable to activate port cgal. Use
'port -f activate cgal' to force the activation.

How can I fix this without forcing the activation?

Many thanks

Ted
