Changing resolver from lts-5.11 to lts-6.1 triggers "Missing build tools" error #2235
Description
Snowdrift at eabedbd builds fine. If I change to using lts-6.1, however, I get the error that mentions #595 (reproduced below).
$ stack build
No packages found in snapshot which provide a "hsc2hs" executable,
which is a build-tool dependency of "skein". Missing build-tools may be
caused by dependencies of the build-tool being overridden by
extra-deps. This should be fixed soon - see this issue
