it is however. the same happened to me.

you just need to run

cabal install pcre-light --extra-include-dirs=/opt/local/include --extra-lib-dirs=/opt/local/lib

My location is /opt/local, since I installed pcre via macports

sudo port install pcre

Bue I think pcre is installed by default in

/Developer/SDKs/MacOSX10.5.sdk/usr/

Just check it out and report back.

Good luck,

hugo

Looks like pcre.h (the libpcre C library ) isn't installed.
