ekg cannot be turned on for Windows builds

[S11001001]

This is with Haskell Platform 2014.2.0.0, ghc 7.8.3, cabal 1.20.0.3, Windows Server 2008 R2.

The working setup

As of 0f5367c

network-2.4.2.3 is preinstalled.

But without trifecta >=1.5.1.2 or blaze-markup <0.6.3, we have the trifecta/blaze mismatch bug.

Fresh sandbox with trifecta >=1.5.1.2, blaze constraint removed

Installs network-2.6.0.2, but:

Same as last, but install with --constraint="network<2.5"

The idea is to force use of the already-installed network 2.4.2.3, but
this causes:

network-2.4.2.3 (latest: 2.6.0.2) (reinstall) changes: parsec-3.1.5 -> 3.1.8

Which results in the same error when building ermine.

@joshcough reproduced with no Platform, GHC 7.8.4, failing while building a dependency that depends on network; see output.
