Hi,

I tried to build Ruby 1.9.1p129 on a 64 bit openSUSE 11.0 system.
It failed with the following message.
Is this a bug in Ruby 1.9.1p129?

./miniruby -I./lib -I.ext/common -I./- -r./ext/purelib.rb
./enc/make_encmake.rb --builtin-encs="ascii.o us_ascii.o unicode.o
utf_8.o" --builtin-transes="newline.o" enc.mk
