Possible bug in make install script

[luccareinehr]

When I run make install, I get this error:

--- installing executable to /usr/local/bin
--- installing run-time files to /usr/local/lib
make[2]: *** No rule to make target '/usr/local/lib/netgen/python', needed by 'install-tcl'.  Stop.

Here's the installation log:

When I run the netgen command, it still seems to work. Perhaps it's just the warning?
