cabal install mysql-simple fails

[dhjdhj]

Tried to just install from cabal. Amongst the many weapons (I mean errors) were

.....
Configuring mysql-0.1.1.6...
setup: The program 'mysql_config' is required but it could not be found
.....
.....
.....
Building pcre-light-0.4.0.2...
Preprocessing library pcre-light-0.4.0.2...
Base.hsc:103:10: fatal error: 'pcre.h' file not found

include <pcre.h>

....

Fails same way if I pull this source

Seems like this can help

sudo apt-get install libmysqlclient-dev

[timerg]

I met the same pcre-light install error on Macosx.
If you have installed brew, try run brew install pcre or brew upgrade pcre can solve the problem
