port fails to convert file_map to file_map.db after db file repair using /contrib/repairfilemap.2.tcl

[dmichael.williams@…]

Following advice on the Problem HotList I was trying to repair a corrupt file_map.db file with repairfilemap.2.tcl. Followed instructions to the letter; ran script -> file_map created and then renamed existing .db file. However, when port command invoked in order to get port to convert old style file to db format, port fails like so:

 # sudo port deactivate R

--->  Deactivating R
Converting file map to new format (this may take a while)
Error: port deactivate failed: Is a directory

When port is invoked using the provides option it fails more verbosely like so:

# sudo port provides /opt/local/etc/lynx.cfg 

Converting file map to new format (this may take a while)
Is a directory
    while executing
"filemap set file_map [lindex $f 0] [lindex $f 1]"
    (procedure "open_file_map" line 42)
    invoked from within
"open_file_map 1"
    (procedure "receipt_flat::file_registered" line 4)
    invoked from within
"${macports::registry.format}::file_registered $file"
    (procedure "registry::file_registered" line 3)
    invoked from within
"registry::file_registered $file"
    (procedure "action_provides" line 13)
    invoked from within
"$action_proc $action $portlist [array get global_options]"
    (procedure "process_cmd" line 92)
    invoked from within
"process_cmd $remaining_args"
    invoked from within
"if { [llength $remaining_args] > 0 } {

    # If there are remaining arguments, process those as a command
    set exit_status [process_cmd $remaining..."
    (file "/opt/local/bin/port" line 3676)

I also tried the older version of the script to no avail though, interestingly enough, the file_map file created was identical to that created by the newer version.
