The following change in .cabal file may solve the problems:---
flag base4
description: Choose base-4 if possible
default: True
library
if flag(splitBase)
if flag(base4)
Build-Depends: base>=4, old-time, time, bytestring, containers,
old-locale
else
Build-Depends: base>=3, old-time, time, bytestring, containers,
old-locale
else
Build-Depends: base<3
Build-Depends: mtl, convertible >= 1.0.1, utf8-string
---
It works for me and I *think* will also work for other setups, most notably
GHC 6.8.*.
All best
