GHC and dynamic linking

I foggily remember previous versions of GHC being unable to create programs that use dynamic links to libraries. Is this the case and, if so, is it still an issue? Static linking is not an option due to licensing issues. I'm interested in GHC 6.6.1 and 6.8.1 on Windows, Mac (PowerPC and x86), and Linux (x86). Thanks in advance, Richard
