 I noticed this because it resulted in the PPA builds of GHC HEAD failing;
 I was able to hunt this down to bdd2d2862e248948efafa8ba4219e94825ddf21a
 which updated `libraries/Cabal`;

 Basically, the following invocation (where `ghc`/`alex`/`happy`/etc. can
 only be found in `/opt/ghc-stage0-toolchain/bin`, and nowhere else; so
 this relies on `configure` to capture their absolute locations; however,
 this is not what causes the failure below)

 {{{#!bash
 ./boot

 PATH=/opt/ghc-stage0-toolchain/bin:$PATH ./configure

 make sdist-ghc
 }}}

 results in
