digikam - khelpcenter and trash problems

[Clayton Ginsburg]

Hi,

I have recently installed macports for the purpose of using digikam.  So 
far it is working wonderfully except for two issues I would love 
assistance resolving

1)  When I try to delete a photo I receive the error "
Could not start process Unable to create io-slave:
klauncher said: Unknown protocol 'trash'.
.
"
I would like the ability to delete photos from within digikam or if this 
is not possible, does anyone have a suggested procedure on a work around 
(e.g. delete from finder, force digikam database to update, etc...)

2) When I try to use the help functionality of digikam(or any kde 
program) by choosing Help -> digikam handbook I receive the message "
Could not launch the KDE Help Center:

Could not find service 'khelpcenter'.
"
I do see a program installed called "khelpcenter.app" in 
/Applications/MacPorts/kde4 that opens just fine, but does not contain 
the digikam handbook.

Any suggestions would be much appreciated.

Details of my system

2010 15" MB Pro running Snow Leopard 10.6.8 with XCode 3.2.6 installed 
and MacPorts 2.1.2
