Font error after installing Leopard?

Question

Leopard is great and fun and Pages works great. B u t. Every time I open anything or create a new document I get an error message that says: "Some warnings occurred. Would you like to review them?" Then if I choose to review the errors, it says the font Helvetica-Narrow has been substituted for the missing font Helvetica.
And no, I haven't messed with the fonts at all.
Got ideas on how I can make it stop with the annoying message?

I have now solved this issue. I have posted it elsewhere but I'll put it here also:
This is the definitive solution to the Helvetica Narrow problem with Pages.
1.Open Font Book.
2.On the left hand side you will see a Column headed "Collection" and beneath this, you will see the following: "User", "Computer", and maybe some other things. Click on "User"
3. Turn your attention to the next Column which is headed "Font". At the bottom of this column you will see a plus sign (under the FONT column) . Click on this plus sign. You will then be asked to select a font file.
4. You need the following path: HD/system/library/fonts. Inside the fonts folder choose "Helvetica.dfont". This will now be installed in your user folder.
5. Close up and your done.
