Right. But what I should have said is that changing the path for the 32 bit version can easily disrupt existing toolchains. For instance, someone who wants to link both C, C++ and D code together is likely not using DMD as the driver for the linker, which implies the use of a hard-coded path to phobos; in this case changing the library's path will break things.

An option would be to keep the 32-bit version as is, and put the 64-bit version in lib64. Or you could add a symlink lib/libphobos.a pointing to lib32/libpobos.a which would keep things working as before.

Or, on the other hand, people like me can also update the toolchain (in my case that'd be when the Mac OS X version is ready).
