I also tried with newest version from R-Forge (svn checkout), but I can not fit
the log-normal mixed model at all. Using the same code as in previous mail I get

> tmp <- lmer(y ~ ai + bi + (1 | ci),
+             data=pod,
+             family=gaussian(link="log"))
Error in mer_finalize(ans, verbose) : 
  General form of glmer_linkinv not yet written
