Cant assume Saxon script found is from EXPath

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Run the 0.4.0rc1 on Fedora Core 16

What do you see instead?
Creating Test Stylesheet...
Command line option -x requires a value


What version of the product are you using? On what operating system?
0.4.0rc1 on Fedora Core 16 AMD64

Please provide any additional information below.
The problem is at line 56 of the xspec.sh script. You cannot assume that if you 
find an executable called 'saxon' then it is from the EXPath project. In the 
case of Fedora 16, there is a 'saxon' executable installed in /usr/bin which is 
Saxon8 and is installed by YUM as a system package.
