I suppose in contrast to the version from HackageDB, which I got myself on monday, the darcs version works with ghc >= 6.6, or I probably would have heard about it. So I'll try to get me that, only where?
I'd already tried that, but $ darcs get --partial http://www.cse.unsw.edu.au/~dons/hs-plugins/ Invalid repository: http://www.cse.unsw.edu.au/~dons/hs-plugins
darcs failed: failed to fetch: http://www.cse.unsw.edu.au/~dons/hs-plugins/_darcs/inventory ExitFailure 1
The file system was down here, sorry. Should be up now. $ darcs get http://www.cse.unsw.edu.au/~dons/code/hs-plugins/
Is my darcs too old (version 1.0.5) or is the repo actually broken?
AFAIUI, version 1.0 will work with ghc6.6 on non-Windows platforms. It's been broken on Windows for some time, and I don't really know why. As you seem to be on Linux, this shouldn't affect you.

Well, again, the .tar.gz from HackageDB is tagged 1.0, it definitely doesn't work with ghc-6.6.1 on my linux. And it apparently was packed in February, so it shouldn't be too out of date.
Let me summarize my findings so you guys have something to reason from. 1) if I compile the module and execute the binary, I get $ PlugTest PlugTest: /tmp/MKtHcN2822.o: unknown symbol `pluginszm1zi0_AltDataziDynamic_toDyn_closure' PlugTest: user error (resolvedObjs failed.)
You must use the darcs version with ghc > 6.6
2) If I load the compiled code into ghci, load cannot ever find the symbol resource, originally that is because it looks for main_resource_closure instead of ModuleName_resource_closure. Now I changed the code in System.Plugins.Load, so that load does look for the correct symbol, with baffling results. In compiled code, all loads still fail. If I load interpreted code into ghci, the first load succeeds, hooray! But all subsequent loads fail, until I :reload (sometimes) or :load PlugTest (that always worked so far). How come? When I added debugging output, I could see that it looked for the correct symbols in the correct .o files, but only the first found the symbol. Very peculiar.
Could somebody please enlighten me?
The module name issue is fixed in the darcs version. -- Don
