subversion-1.5.0_rc4.ebuild DOES include the following snippet: -- cut -- if use python || use perl || use ruby; then myconf="${myconf} --with-swig" else myconf="${myconf} --without-swig" fi -- cut -- but DOES NOT have dev-lang/swig in DEPEND - thus compilation fails after depclean. subversion-1.4.6.ebuild works fine...
This bug report is INVALID! Subversion tarballs contain SWIG-generated files and they aren't regenerated even when SWIG is installed. --with-swig only enables some rules in Makefile which are used to build bindings.
