I'm trying to compile Ruby 1.9 on my web hosting provider's box running Fedora Core 4. It compiles just fine, but when I do "make install" and try to generate the docs, it chokes.

Here is the error message:
---------------------------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------------------------

which shows that the culprit is time.c file. The funny thing is that generating docs for just this file by itself works OK:
----------------------------------------------------------------------------------------------------------------------

$ ./miniruby  ./runruby.rb --extout=.ext  -- "./bin/rdoc" --all --ri --op ".ext/rdoc2" time.c

At home, on Fedora 8 box everything works fine.  Any help, please?

Thank you.
