Well, it seems that simply adding wget.exe to my search path did in fact
fix the issue. It hasn't hard to find with Google, but a small note to
that effect somewhere in the documentation would be quite nice.
Seriously, you have literally *no idea* how much trouble I've just had
trying to achieve the simple task of getting Leksah to work. Every
imaginable thing has gone wrong. Each impediment is fairly trivial in
itself, but the sheer volume of them is... straining my patience!
- Darcs now needs wget in order to work. [Easy to fix once you work out
- Leksah needs Gtk2hs, but I have GHC 6.8.2. [Thank the Maker for gname
- I've have never found the URL for the unofficial Gtk2hs build to fix
- Leksah needs something called "binary". [Once you figure out that
that's a package and you're supposed to get it from Hackage, it's quite
easy to find. Figuring out what to do with a tarball on Windows isn't
that amusing. However, for once, Cabal did actually build and install it
- When I try to install Leksah, it complains that a PNG file doesn't
exist. [My guess is the author's Darcs repo contains it, but they forgot
to tell Darcs.] So I _manually edit_ the Cabal file. [Eeek!] Obviously
Cabal now makes me reconfigure and rebuild, but the program now installs
- Gee, now I wonder *where* exactly Cabal installed it? Oh well, it
seems to have put the binary in my search path anyway - that's a nice
touch. Now, let's see what this IDE actually looks li-- oh you have GOT
to be KIDDING me! It can't find the right GTK DLL?!?
By now, I've been trying to "try out Leksah" for about an hour. As you
can see, each problem is pretty small [although the "manually edit Cabal
file" bit was scary]. However, add together enough small problems and
you end up with a very frustrating experience. When it takes you 10
minutes or so to fix each problem, 6 small problems = 1 hour of your
life. It adds up rather fast. :-(
At this point, my best guess is that the unofficial Gtk2hs binary is
broken somehow. [Although I don't recall hearing anybody yelling about
it...] Maybe tomorrow I'll try again on my other box that has an older
GHC on it and see how that goes. For tonight, I'm just too frustrated to

bit exasperated right now. I'll get over it. By tomorrow, this will
probably seem very amusing... but right now it's quite late, and I'm
