Heya neoxed... I don't believe any TCL based script worked with any 5.8.6+ release. Shared memory scripts also had issues although it's possible recompiles might have worked.
Pretty much your choice today is the magic 5.8.5 or use the latest v6.2 release. The 6.x releases resume shared memory compatibility with the v5 releases that post 5.8.6+ broke and TCL works again. The list of changes is pretty lengthy but the most significant to your work might be the addition of an optional field to the section part of ioftpd.ini. If you don't use it things would be compatible, but I think the default uses it as an example but doesn't really need to. I'm going from memory, but I think I saw an nx script comment about the new section definition breaking something.
If you use relative symlinks then the latest release is bound to be an issue for the script since everything prior was wrong and fixing it changed their behavior.
Of course, if you find you really need something added, just let me know
