	There's the ${prefix}/etc/macports/prefix.mtree file and whatever is  
listed there is created by MacPorts itself during the pre-destroot  
stage as the installation bed for a destrooting port (destroot_start  
proc in base/src/port1.0/portdestroot.tcl [1]). Once the destroot  
stage is done, whatever directory in the destroot that's void of any  
files (that is, the destrooting port didn't place anything in them)  
gets pruned during the post-destroot closing stage. Therefore,  
anything else that's not in the default mtree needs to be created  
manually and anything you intend to keep for installation even if  
empty has to be safeguarded through a destroot.keepdirs clause.

	HTH! Ping me if not ;-)

	I wonder if we still use the mtree file installed in ${prefix}/etc/ 
macports/ for something? Anyone care to destroot a port after moving  
it aside and report any findings? (comparing to destrooting after  
moving the one in /opt/local/share/macports/resources/port1.0/ 
install/ aside would be ideal).
