I have just noticed that expect does not want to compile with tcl8.0.5. Its configure script expects tcl8.2.? at least. Additionally the scriptics.com is down now, and there are no mirrors anywhere to be found ?!
The sources fail to compile on a number of symbols that (should ?) be defined in the tcl*/generic/tclPort.h file. There is also no previous (older) copy of expect sources anywhere to be found on the web (i.e. one that compiles with tcl8.0.5).
