apache22 web root directive

[Eric]

Is there a directive to add to make.conf or anywhere else to tell ports 
what directory my webroot is? when i was running apache20, things like 
mailgraph installed files in the proper location. Recently I just 
updated to apache22 and now mailmail still insists on creating 
directories under the old directory layout. is this a mailgraph port 
problem or do I have a missing directive somewhere telling ports where 
my document root is?

Thanks!

Eric
