Current ruby.spec declares: BuildRequires: db4-devel Berkeley DB 4 is deprecated in favour of version 5. Please change build- and run-time dependency from db4 to libdb. (This is good to prevent crashes when dlopening shared objects compiled against libdb.so.)
Thank you for heads ups. Fixing it just in Ruby 2.0 branch, which will go into Rawhide soon. No need for change in older releases IMO.
Fixed in ruby-1.9.3.362-26.fc19 (ruby 2.0 will also use libdb(5))
In trying to use ruby-2.0.0.247-15 from rawhide to build an rpm for el6 I ran into 'libdb-devel' not being available... am I missing something or should I just build it against db4-devel on el6?
db4-devel should be the right choice for el6.
