i'm trying to run my ant script within eclipse, and get an error message
about it not being able to find a modern compiler. any ideas why this
would happen and what can be done to fix? eclipse builds the java files
in my project just fine when editing and such.

Mark,

You need to add a jdk tools.jar to the Ant runtime classpath using the Ant
runtime preference pages.

If you start Eclipse using the -vm arg so that Eclipse is launched using
JDK install, Eclipse will automatically add the tools.jar to the Ant
runtime classpath.

Eclipse has its own compiler. To use this with Ant's javac you will need to
set the build.compiler property.
More details can be found at
http://eclipsewiki.swiki.net/118#compiler
and

Adding tools.jar (jdk 1.4) throw : BUILD FAILED:

(Unsupported major.minor version 48.0)

And if I add tools.jar (jdk 1.3) it is ok, but my source use jdk 1.4
functionnality and so it can't be compiled with tools.jar (jdk 1.3).

Any idea ?
