The ant script cannot find its home

           Summary: The ant script cannot find its home
           Product: Ant
           Version: 1.5.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Wrapper scripts
        AssignedTo: dev@ant.apache.org
        ReportedBy: christos.kloukinas@imag.fr

The ant script tries to find out its home by looking at the path of the file it
is linked to (when it is a link) in line 57 of the script ant.
If I understand correctly, the check is for a local link (./ant-some-version)
versus a complete path (/some-path/ant-some-version).
In my installation it is a relative link (../../relative-path/ant) and the
script tries that (../../relative-path) as the ANT_HOME, which fails.

Solution:
Change the following:
<pre>
    if expr "$link" : '.*/.*' > /dev/null; then
        PRG="$link"
    else
        PRG=`dirname "$PRG"`"/$link"
    fi
</pre>
With the following:
<pre>
    if expr "$link" : '.*/.*' > /dev/null; then
        if [ -d ${link}/. ] ; then
            PRG="$link"
        else
            # Most probably it is a relative link ...
            PRG=`dirname "$PRG"`"/$link"
        fi
    else
        PRG=`dirname "$PRG"`"/$link"
    fi
</pre>
