The wiki page description of how to build LDC:
http://wiki.dlang.org/Building_LDC_from_source

... seems to be missing a couple of dependencies, namely zlib and libedit (required for -lz and -ledit).  The LLVM version constraints are also probably a little outdated.

Happy to tweak the page myself at some point, but thought I'd raise it here first in case someone wants to offer some input.

zlib comes with phobos, so it isn't listed, as that list only consists of external dependencies.  I don't know about libedit, where is it actually used?

LLVM itself has started to depend on those somewhat recently. When linking LLVM statically (which is the default), they are added to the list of ldflags that llvm-config reports.

Ah, I see, didn't know that.

On both zlib and libedit ... ?

If I remember correctly, yes. I'm not sure which components require it, but llvm-config spits them out as part of the ldflags.

Bit late to be following up on this, but I've added them to the wiki page:
