Linux distinguishes between runtime and linkable libraries; you probably need to install the libc6-dev package to get the latter. (This is not a Haskell-specific issue; configure is using a C program to test the link.)

But libc6-dev is already the newest version.

Then you'll have to check config.log (this probably means doing the build manually with "cabal unpack darcs" and then running "cabal install" without a package name from the directory with the darcs.cabal file) to see what's going wrong.
