link problem

[Kazu Yamamoto ( 山本和彦 )]

Hi,

GHC head of today cannot link installed libraries. When I tried to
install "lifted-base", the following error occurred:

----
[6 of 6] Compiling Control.Concurrent.Lifted ( Control/Concurrent/Lifted.hs, dist/build/Control/Concurrent/Lifted.o )
/usr/bin/ld: cannot find -lHSmonad-control-0.3.2.1-ghc7.7.20130430
/usr/bin/ld: cannot find -lHStransformers-base-0.4.1-ghc7.7.20130430
/usr/bin/ld: cannot find -lHSbase-unicode-symbols-0.2.2.4-ghc7.7.20130430
collect2: ld returned 1 exit status
cabal: Error: some packages failed to install:
lifted-base-0.2.0.4 failed during the building phase. The exception was:
ExitFailure 1
----

Each library names followed by "-ghc7.7.20130430". Is this correct?

Note that "lifted-base" was able to be installed in a few days ago.
