Error when emerge boost package

[冯超]

Hi,

When emerge boost, the following error message is shown:
"already installed, this should no happen"

I checked the etc/portage/installed file. Only boost-* package are 
installed:

win32libs-bin/boost-headers-1.47.0
win32libs-bin/boost-program-options-1.47.0
win32libs-bin/boost-python-1.47.0
win32libs-bin/boost-system-1.47.0
win32libs-bin/boost-thread-1.47.0


So the code in emerge\bin\portage.py line 791 thought boost-headers is 
boost- :
    elif line.startswith( "%s/%s-" % ( category, package ) ):
         utils.die(package + "already installed, this should no happen" )

The parser code above should be updated to handle this boost special case.
