this is a problem that's been driving me nuts ever since i first tried it. i can create simple, minimal scripts in Python, Perl, and PHP that run flawlessly on the first try with minimal effort, both on my local testing system (Apache 2.0.52 and Ruby 1.8.2) and on the server my personal site is hosted on (Apache 1.3.33 and unknown version of Ruby - i'm trying to find out). but no matter what i try, i simply can not get even the most minimal ruby script to function: #!/usr/bin/env ruby print "Content-type: text/html\n\n" print "<html><body>Hello World!</body></html>\n" it runs perfectly fine at the console, no warnings, no errors, no problems. but as a CGI script, it's another story: i get an error 500 and the cryptic (and seemingly common) "Premature end of script headers". no other warnings or errors. if i simply change "ruby" to "python" on the shebang line, the above script magically works with no other effort on my part. i'm going insane because nothing, AFAICT, is wrong. the server is correctly set-up, permissions are correct, ownership is correct, ruby is installed and working, yet NOTHING seems to coax it into working. it repeatedly reports this incredibly uninformative "Premature end of script headers" error. is there something i could have missed? a possible misconfiguration? or does ruby just hate me?
