Turns out the installed tclsh needed an Itcl library that didn't exist under the /usr/local/smartbits/smartlib/lib directory structure. Once I installed itcl and then copied the library files to the correct directory structure I was able to get this working. Thanks for the patch, it was the only way I was able to figure out the issue......incidentally I was using the wrong tclsh (one of them had itcl already installed and one didn't) which is why tclsh smb.tcl worked. Thanks again for the help!!!!
