@proppy I have followed native installer in Centos7. But facing issue while running

flow.tcl

source silicon-env/bin/activate 
(base) flow.tcl -design spm
no files matched glob pattern "/usr/share/tcltk/tcllib*"
    while executing
"glob -type d "/usr/share/tcltk/tcllib*""
    (file "/home/vijayan/Open_RTL_GDS_Flow/silicon-env/share/openlane/install/env.tcl" line 6)
    invoked from within
"source $::env(OPENLANE_ROOT)/install/env.tcl"
    (file "/home/vijayan/Open_RTL_GDS_Flow/silicon-env/share/openlane/flow.tcl" line 19)
    invoked from within
"source "$::env(CONDA_PREFIX)/share/openlane/flow.tcl""
    (file "/home/vijayan/Open_RTL_GDS_Flow/silicon-env/bin/flow.tcl" line 3)
