# StringTemplate has a cyclic dependency on ANTLR 3. The runtime classes
# are needed at build time and runtime and the tool is also needed at
# build time. To break out of this, we use a prebuilt copy of ANTLR 3 at
# build time and manually register a dependency on the package, which
# will be present at runtime thanks to this PDEPEND. No prebuilt
# software is actually installed onto the system.
