[ptp-dev] Problem installing CDT 5.0.1 build with PTP M3 build.

[Dave Wootton <dwootton@xxxxxxxxxx>]

I had a problem installing the CDT 5.0.1
9/12 build on my Windows XP system after installing PTP 2.1. I had this
problem with the M2 build and still had it with the M3 build, but this
time I saved the error logs.
I initially installed all of PTP 2.1
except the TAU Enabler plugins, restarted Eclipse, then tried to install
all of CDT except the two uncategorized plugins (source code)
When the CDT install was checking dependencies,
I got a popup warning me of a problem with dependency checking and the
following two messages which also show up in my error log 
Problems resolving provisioning plan

No solution found because the problem
in F:\DOCUME~1\Owner\LOCALS~1\Temp\p2Encoding52070.opb is unsatisfiable.

I have no idea what a *.opb file is.
I tried looking for it in my Documents and Settings directory but was unable
to find it

I ended up uninstalling the PLDT amd
PLDT LAPI plugins and the problem went away.

Anyone seen anything like this?
