Thanks, already solvedby reinstalling Ruby 1.9.1 from sources with options:

  ./configure --prefix=/usr/local/ --program-suffix=1.9

Then I get:

/usr/local/bin# ll
-rwxr-xr-x 1 root root 4,4K 2009-04-05 16:49 erb1.9*
-rwxr-xr-x 1 root root  791 2009-04-05 16:49 gem1.9*
-rwxr-xr-x 1 root root  323 2009-04-05 16:49 irb1.9*
-rwxr-xr-x 1 root root 1,3K 2009-04-05 16:49 rake1.9*
-rwxr-xr-x 1 root root  415 2009-04-05 16:49 rdoc1.9*
-rwxr-xr-x 1 root root   78 2009-04-05 16:49 ri1.9*
-rwxr-xr-x 1 root root 5,4M 2009-04-05 16:48 ruby1.9*
-rwxr-xr-x 1 root root  252 2009-04-05 16:49 testrb1.9*


And later I do symbolic links from /usr/bin to there, i.e:

  /usr/bin/ruby --> /usr/local/bin/ruby1.9

Thanks.
