Dear cafe,

Following the instructions at http://matt.freels.name/2010/hdbc-mysql-os-x.html I successfully installed HDBC-mysql on my Mac!

However when doing a "cabal install" in a local package which depends on HDBC-mysql, cabal proceeds to reinstall HDBC-mysql (is this a bug? see my other email from a few moments ago), this time unsuccessfully because it is using the unpatched cached version downloaded from hackage. This breaks my installation: ghc-pkg list colors the package red.

Now comes the weird part. :-) I try to reinstall HDBC-mysql with my unpacked, patched version. It fixes my installation of HDBC-again, even though it exits prematurely with some errors! I've included the output at the end of this email.

I wonder:

Where do these errors suddenly come from? The first time the installation went without trouble.

How come it fixes my installation even though it reports errors?

Thank you in advance,

Martijn.



Output of "cabal install --extra-lib-dirs=/usr/local/lib:" in a local version of HDBC-mysql, patched according to http://matt.freels.name/2010/hdbc-mysql-os-x.html:
