Came up with error

[Earl Larsen]

I cvs my ports and used potsdb -Uu. And it came up with the fallowing error:

#main portsdb -Uu
Updating the ports index...Generating Index.tmp-please wait... 
twig-2.7.7_1-"www/mod_php4-twig" non_existent - - dependency list incomplete 
===> www/twig failed

***Error code 1

portsdb:index generation error

I ran pkgdb -fu and pkgdb-F to see if that would help. My Freebsd version is 
4.10. I do not know ware I can get my ports configuration. And the attachment 
is my make.conf settings from /etc/make.conf.
