Description of problem:
I just installed asciidoc and tried to generate a PDF from a simple .txt file, but a2x failed because it couldn't find fop.sh. This continued to happen even after I additionally installed the fop package.

Version-Release number of selected component (if applicable):
asciidoc-8.2.5-4.fc11.noarch
fop-0.95-3.noarch


How reproducible:
Always.

Steps to Reproduce:
1. install asciidoc
2. create a simple asciidoc source file
3. try generating a PDF with a2x
4. install fop
5. re-try generating a PDF with a2x
  
Actual results:
$ sudo yum install asciidoc
...
$ echo "Title
> =====
> 
> Blah" > /tmp/test.txt
$ a2x -v -f pdf /tmp/test.txt
a2x: failed: cannot find required program: fop.sh
$ sudo yum install fop
...
$ a2x -v -f pdf /tmp/test.txt
a2x: failed: cannot find required program: fop.sh

Expected results:
a2x should find all the required tools (without me hunting down for them) and successfully generate /tmp/test.pdf

Additional info:
I haven't experienced this on another F11 machine with exactly the same asciidoc version. I'll have to check if it has fop installed and whether it might have fop.sh in ~/bin/.
