Database/HSQL.hsc:66:7: Could not find module `System.Time': it is a member of package old-time-1.0.0.0, which is hidden vigalchin@ubuntu:~/Desktop/hsql-1.7$

I have a global ghc installation plus a local one off my user directory. In any case, when I do "ghc-pkg list" .... old-time-1.0.0.0 is not hidden. ???? Bottom line is how do I install DB libraries with least pain??

Is old-time listed in the dependencies of the HSQL package? Problem is probably that many functions moved from 'base' to smaller packages like 'old-time' but package maintainers did not move to new compilers and thus new package structure. It's very inconvenient, but a known issue.
