instead of Ruby's.
When older ERB is installed but Ruby is still 2.6.0, this may cause
error like:
```
Traceback (most recent call last):
5: from ../src/tool/generic_erb.rb:36:in `<main>'
4: from ../src/tool/generic_erb.rb:36:in `map'
3: from ../src/tool/generic_erb.rb:43:in `block in <main>'
2: from ../src/tool/generic_erb.rb:43:in `block (2 levels) in <main>'
1: from /opt/local/lib/ruby/2.6.0/erb.rb:873:in `result'
/opt/local/lib/ruby/2.6.0/erb.rb:869:in `block in result': no implicit conversion of Hash into Integer (TypeError)
```
For safety, I changed this to check ERB's version. See also: r62529.
