Ruby 1.9.1 p429 was released BUT SEGV occurs

Yesterday, Ruby 1.9.1 p429 was released. So I download from here and install its package like this entry. But, SEGV occur in make instrunction.

SEGV shows below:

./miniruby -I./lib -I.ext/common -I./- -r./ext/purelib.rb  ./tool/generic_erb.rb -c -o encdb.h ./template/encdb.h.tmpl ./enc enc
