xinstal not making directories

[Scott Haneda]

     # Create 'logs' directory in ASSP base
     xinstall -d -o _assp -g _assp -m 0755 ${destroot}${assp_base}/logs

That will do nothing, unless I put something in it:

     xinstall -m 0644 ${worksrcpath}/mod_inst.pl ${destroot}$ 
{assp_base}/logs/mod_inst.pl

How can I create an empty directory in MacPorts?
Is this correct behavior?
