I just upgraded to Ubuntu 11.10 (from 11.04). I have attached the error message. It looks like it is a problem with a reference to `clock_gettime`.

Any suggestions?

Ubuntu made some changes to the linker. See if this information helps and report back. This is from a post in digitalmars.D

"Changes to gcc or ld in Ubuntu 11.10 require a small addition to prevent linker errors referencing librt. "-L-lphobos2" needs to be added to DFLAGS before "-L-lrt". I spent a long time trying to figure the problem out before I realized that gcc was tacking on a -lphobos2 to the END of the command (after the -lrt flag).

It will be fixed with the next release. -L-lrt won't even be needed in dmd.conf anymore. It's being linked in by the compiler just like libpthread is.

Yup, that did the trick! Everything is working just fine now as far as I can tell.

It's a "bug" fixed in the upcoming compiler release:
