[Distutils] Installing files with syntactic errors

In my package, I have a few files which are syntactically incorrect in Python 1.5 (since they use Unicode literals). Those files are not used in Python 1.5, but are part of a package, and are used in Python 2.0 and later.

When running install_cmd on Python 1.5, installation aborts when trying to byte-compile files. I know I can invoke install_cmd with --no-compile, but I still would like to generate byte code for all the other files.

So I'm looking for a way to either skip byte-compilation for a single file, to silently procede in case of byte-compilation errors, or to exclude a single module of a package from both building and installation.

Any suggestions are welcome.

TIA, Martin
