Hi,

*** Warning: linker path does not have real file for library -ltcl86.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libtcl86 but no candidates were found. (...for file magic test)

*** Warning: libtool could not satisfy all declared inter-library
*** dependencies of module tclmsgque.  Therefore, libtool will create
*** a static module, that should work as long as the dlopening
*** application is linked with the -dlopen flag.

The Attachment has the link error ...
the important part is...
