git-update-cache:

[Sam Ravnborg <sam@ravnborg.org>]

While trying to execute:
git-update-cache -- drivers/Kconfig drivers/net/Kconfig net/Kconfig

I receive the following error:
git-update-cache: symbol lookup error: git-update-cache: undefined
symbol: deflateBound


I have fetched a clean tree from kernel.org, and cloned it using
cg-clone.
Modifications are done in the cloned tree and the error is seen when
trying to do a cg-commit (that does the git-update-cache).

When this error is seen a file .git/index.lock is left and next
invocation of git-update-cache faild due to this but deletes the file.
Third invocation show the same error again.

To my best knowledge I have a working zlib installed.

Any help really appreciated!

	Sam
