Yes, it works, but it should not...

... no, it's not the state: In the file tcl-glue.c the function
"char *STk_tcl_getvar(char *name, char *env)" does not return
a value. Patch it...
$ diff tcl-glue.c.orig tcl-glue.c
192c192
< STk_convert_for_Tcl(V, &dumb);

... and it works under Solaris. I do not know why it works without patch
on Linux? Perhaps the Linux-Kernel is more intelligent and finds little
errors like this ;-)
