Profile Guided Optimizations on VS2005 Std

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

After reading a bunch of articles saying that Profile Guided
Optimizations (PGO) is the greatest thing since sliced bread, or at
least Link Time Code Generation for improving app speed, I decided to
give it a try. I have a VS2005 .sln with a bunch of helper DLLs, a
bunch of projects that build .libs, and one exe that has a fair amount
of code, and pulls in those .libs. Under Project properties -> General
-> Whole Program Optimization, I selected 'Profile Guided Optimization
- Instrument', and hit build. At the bottom, I get:

19>Linking...
19> Creating library ..\debug\bzone.lib and object ..\debug\bzone.exp
19>Generating code
19>c:\src\BZ2\Source\CORE\utilsys\varfile.cpp : fatal error C1350: error loading dll 'pgodb80.dll': dll not found

Scanning C:\Program Files\Microsoft Visual Studio 8 , I don't see
that DLL anyhere. I'm using Visual Studio 2005 Standard, as handed out
at one of the launch events for it. I've even tried uninstalling it
and reinstalling from the CD, and it gives me the same problem --
it allows me to select PGO, but I get the link error above. It seems
rather misleading to allow selection of a menu item if one can't
actually use it.

I've also got VS2008 Standard from the launch event. Is anything
any different in that product?
