err messages during make install-doc

[Mark]

I'm installing ruby for the first time on OS X 10.4.11. I'm following
the directions written in Simply Rails 2, the section on install Ruby on
a Mac.

I installed readline, then I followed the directions for installing ruby
1.8.6. I ran "sudo make install" - no errors. When I ran "make
install-doc", I get the following errors:

followed later by these errors:

Running the command "ruby -v" tells me I've got version 1.8.6. But,
should I be worried about these errors?
