Hi,

Folks, I want to get some help from anyone on the list that has tried  
to build ruby on openbsd. I currently have OpenBSD 4.5 and I’m  
building ruby-1.9.1-p243. I was able to run ./configure without any  
problems but when i build gmake I get the following:

$gmake  
echo executable host ruby is required. use --with-baseruby option.;  
false ./tool/generic\_erb.rb -c -o known\_errors.inc  
./template/known\_errors.inc.tmpl ./defs/known\_errors.def  
executable host ruby is required. use --with-baseruby option.  
gmake: \*\*\* [known\_errors.inc] Error 1

Any help would be awesomely appreciated.
