The first problem:

You need to add an "ant clean" step before you do the "ant dist" step.

All you did with 'ant dist' was put the existing ".class" files into the 
las.war instead of re-compiling them.

You should see a message like:
[javac] Compiling 111 source files to 
/home/stout/rhs/las/las_servlet/classes

under the "compile:" ant target message to know that the classes are 
being re-compiled.

The second problem relates to a Perl module.  Your URI (we think that's 
the right one) module is "too new" and it's leaving a slash when it 
resolves the file://las.xml url.  The LAS configuration code only checks 
to make sure that perl module versions are 'higher than x.y'.

Try inserting the following lines into configure.pl at line 1651 (just 
before the test for ($module eq 'Template')).

                   } elsif ($module eq 'URI') {

# More recent versions of URI leave an extra slash when resolving 'file://las.xml'.

                     require('DBI.pm');
                     if ($DBI::VERSION <= 1.19) {
                       $found = 1;
                       last;
                     }

After making this change, the configure script should compile the URI 
module distributed with LAS if the currently installed URI module has a 
higher version number than the one we distribute.
