I was seeing this error all of a sudden today while trying to import a CD and it would not add the imported music to my Library.
"The iTunes Library file cannot be saved. An unknown error occured (-54)."
However, I did the following steps listed in an earlier post and it solved the problem without doing anything else.
Go to iTunes, "File", choose export library.
Save the library.xml file on your desktop.
Quit iTunes, delete the library files in the iTunes folder ( I just moved it to the Trash, but did not empty it).
Relaunch iTunes, go to "File", click on "Add to Library" and choose the newly exported library.xml file.
Import CD worked fine after that.
Many thanks for the solution!

@nomond, Ok so I was getting the same error "The iTunes Library file.... (-54)." And I did what you recommended above. I saved the library file onto the desktop, quit iTunes and moved the library files from the iTunes folder to the trash. Then I relaunched and from File clicked "Add to Library" file that was sitting on the desktop.
This made all of my music disappear and I haven't been able to get it back. I know the music is still there somewhere. I have even tried to take the files out of the trash and put them back and nothing?
I am worried now that I have lost my playlists and Genius lists etc. Not to mention I don't even know the best way to map my music back.
Any help would be greatly appreciated I have been without music for a week.

I used Repair Permissions and it seemed to solve the iTunes problem, however, it completely knocked out my HP printer, which I now cannot open. (I get the 'Power PC apps are no longer supported' message.) It was working fine this morning. Anyone know how I can restore it? I've tried everything I can think of and have wasted an hour doing it. Thanks!

This site provides HP drivers and software for all their printers. You could try installing the latest drivers and software for your printer and see if that gets it up and running again. Even if you had the most up to date drivers and software doing a reinstall may be advised as something may have been corrupted or changed when you did the repair permissions.
Good luck. Let us know if this helps.
