[Haskell-cafe] Further installation adventures

I'm trying to cabal install lambdabot. This depends on a squillion  
other libraries, which cabal tries to install, among which is  
readline, which fails to configure as follows.

Configuring readline-
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking for GNUreadline.framework... checking for readline... no
checking for tputs in -lncurses... no
checking for tputs in -ltermcap... no
checking for tputs in -lcurses... no
checking for rl_readline_version... no
configure: error: readline not found, so this package cannot be built
See `config.log' for more details.
cabal: Error: some packages failed to install:
readline- failed during the configure step. The exception was:
ExitFailure 1

 From which I conclude that it can't find the readline library. I have  
all sorts of flavours of readline on my system, so I'll need a bit  
more information about what exactly it's looking for.

It tells me to look in config.log. I presume that this is the config  
log of the cabal package readline, which cabal automatically  
downloaded, unpacked ... and presumably automatically cleaned up at  
the end, because I can't find it anywhere.

Where should I be looking for the relevant config.log?
