FreeBSD ports

[dvelez502 at verizon.net]

Hi, I am running freeBSD 5.1.  
 
I read the handbook on updating the ports system. The  
updated ports were placed in the /home/ncvs/ports. I cd 
to the /home/ncvs/ports/3ddesktop. I typed the usual 
make install clean as root. I gotten this error message: 
 
make: don't know how to make install. Stop 
 
 
But, when I build from the default directory 
/usr/ports/package-name it compiles and install 
the package fine. The 33desktop is not in the 
/usr/ports directory, but in the /home/ncvs/ports 
directory. I want to install this package but I 
get the error above. If you can help, I surely appreciate it. 
 
Thanks
