who exchanged e-mails with me offline while we determined the solution, and
Scott Hanselman, who wrote a blog post at
"bin deploying" MVC 3.  Here's how I got it to work:

 - I added Microsoft.Web.Infrastructure.dll, System.Web.Razor.dll, and
System.Web.WebPages.Razor.dll as local references to my application, and set
"CopyLocal = true" on each of them within the VS project.
 - I added "CopyLocal = true" on System.Web.Helpers, System.Web.Mvc, and
System.Web.WebPages within the VS project.

It appeared to be the missing Razor DLLs that were causing the "unable to
find view" problem; interestingly, this is working without precompiling the
views.  I'll probably switch the views to being precompiled anyway, just to
save that overhead every time the app is started; when this happens, I'm
guessing that I'll probably need to put Carl's engine-tweaking code in the

There is one oddity that remains; the first time I hit the app, I get an
error that the system "does not have access to the key requested".  In
searching for that, I saw something that said that the web server needed
write access to $HOME/.mono.  As the web server runs as www-data, I created
a .mono directory in its home, and chown'd it to www-data:www-data.
 However, when I redeploy the app or bounce Apache, the first hit to the
site still gives me the error.  It's coming out of code in
Microsoft.Web.Infrastructure - it's not a huge deal, but if anyone has an
idea about that, I'm all ears.

Thanks again to Carl for helping me with all this.  I'm so excited to have
MVC 3 running on my Linux box!  I'm wishing that all the programming
languages I have to use on a daily basis had Razor - it's that quick.  :)
