You might want to watch out for a bug in GHC 6.8.2 that means GHC's "- 
static" flag doesn't work. (At least for me, at least on Debian: the "- 
lpthread" flag is passed before the "-lrt" one, and symbols are left  
unresolved as a result.) Apparently the near-to-release 6.8.3 will fix  
this issue.

Presumably dons is using a more recent GHC than 6.8.2, or other (BSD?)  
platforms are not affected.

Note also you may have to tweak sundry .cabal files to add "extra- 
libraries" fields. As an example, I added this to HSQL's PostgreSQL  
backend to get it to statically link:

extra-libraries: pq, crypt, pthread

(If anyone cares you need to build PostgreSQL without kerberos as that  
doesn't seem to statically link any more.)
