inclusion of Network.Curl causes compiler issues and coredumps

the attached program began to show compiler failures (though not always reproducible), and coredumps (again, not always reproducible) once HXT was replaced with Text.XML.Light.

i have taken care to install (and reinstall) packages with cabal-install although many of the packages i use were originally installed with traditional Setup.hs installation and registry.

i'm really not sure what the issue is.

my environment is ghc-6.8.2 on freebsd7/i386. my ghc was installed from freebsd ports. i use cabal-install to manage other packages. this program is the only one i have had issues with. i am attaching the program in its entirety.
