It looks there should have been /usr/lib/tcl8.5... instead.couldn't load file /usr/lib64/tcl8.5/sqlite3/libtclsqlite3.so
When I symlinked /usr/lib64 to /usr/lib then it works OK.
the error seems to be in the file: /usr/lib/tcl8.5/sqlite3/pkgIndex.tcl
It was OK in 13.37.
I don`t know if this is Salix specific or of Slackware origin.
