Checking for scripting languages.

[Tommy Nordgren]

I  need to check for scripting languages (ruby, perl , python 2.x ,  
python 3.0) and generating a script file
depending on what's available.
I do this in the following way
if ruby is available:
cp collect.rb collect && chmod +x collect
if perl is available:
cp collect.rb collect && chmod +x collect

Any Ideas on how to test && generate the output using autoconf?
