How to install ThreadScope on GHC 6.12 in Ubuntu

I've try to install treadScope on my computer for Haskell parallel profiling, I'm using Ubuntu 10 and GHC 6.12. The problem it that I unfortunatlly came out with the following problem. I can't install glade, and the command pkg-config -modversion libglade2.2 return an error, which mean that the glade's .pc file is not found by the system. How can I fix this problem on ubuntu,

Thank you a lot for any answer

More details

here is the error message return by the command cabal install threadscope

Linking /tmp/glade-0.12.02992/glade-0.12.0/dist/setup/setup ...

Configuring glade-0.12.0...

setup: The pkg-config package libglade-2.0 version >=2.0.0 is required but it could not be found.

cabal: Error: some packages failed to install:

glade-0.12.0 failed during the 开发者_开发问答configure step. The exception was: ExitFailure 1

threadscope-0.1.2 depends on glade-0.12.0 which failed to install.

And here is the error message return by the command _pkg-config --modversion libglade-2.0

Package libglade-2.0 was not found in the pkg-config search path.

Perhaps you should add the directory containing `libglade-2.0.pc' to the PKG_CONFIG_PATH environment variable

No package 'libglade-2.0' found
