Thanks a lot Nick,

Just recompiling dmd alone and use the rest from the zip archive worked.
(had to remove L--no-warn-search-mismatch from dmd.conf which is not
supported by CentOS' ancient ld). I thought I would need to recompile
everything to match compiler and libraries.

And it really doesn't help that the phobos src in the 2.053.zip does not
compile (vs phobos on git does).

When dmd goes in the next beta round this will be my first test:
  Can I compile everything in the zip file...

But it would be great if we could convince Walter to build dmd on an
older distro like CentOS 5 (or even 4?) instead.
