Problem with a Qt application portfile

[Linc Davis]

I'm trying to port evolvotron:

http://sourceforge.net/projects/evolvotron

It build with qmake. Works in Fink.

So far, I have this:

PortSystem 1.0

I get as far as this:

--->  Fetching evolvotron
--->  Verifying checksum(s) for evolvotron
--->  Extracting evolvotron
--->  Applying patches to evolvotron
--->  Configuring evolvotron
--->  Building evolvotron with target all
--->  Staging evolvotron into destroot
--->  Packaging tgz archive for evolvotron 0.4.0_0

And then I get this:

Error: Target org.macports.archive returned: error copying "/opt/ 
local/var/macports/build/ 
_opt_local_var_macports_sources_local_graphics_evolvotron/ 
work/.macports.evolvotron.state" to "/opt/local/var/macports/build/ 
_opt_local_var_macports_sources_local_graphics_evolvotron/work/ 
destroot/+STATE": no such file or directory
Error: Status 1 encountered during processing.

The destroot directory appears momentarily in the work directory,  
then disappears. Apparently it's being deleted just before the tgz  
archive is created. I have no idea why.

Passing the -d option to 'port install' has no effect on the build  
output. MacPorts 1.520, Mac OS 10.4.11 PPC, Xcode 2.4.1.

Thanks for suggestions.
