Your fmtutil.cnf has many lines repeated multiple times, which causes many 
redundant format regenerations.  I have no clue how those lines were added.  
The first few entries refer to "pdflualatex.ini", which was removed from TeX 
Live and thus from pkgsrc long time ago.

Does this happen with the up-to-date pkgsrc?  Could you uninstall kpathsea and 
wipe out etc/texmf, and try again?  I do this often on my Mac OS X, but have 
never seen fmtutil.cnf corrupted.

I have been working on removing dependencies on teTeX-bin or teTeX-texmf.  
There remain about 30 such packages, and none of them need all those 
hyphenation patterns.  Once the dependencies are minimized, most of the 
hyphenation packages will become leaf packages, installed by those who does use 
the languages.

Since typical usage of (La)TeX does not require hyphenations for many 
languages, this will be a nonissue then.

If anyone want to help, please search for packages including 
"print/teTeX/" ro "mk/", or directly depending on 
teTeX-bin, and reduce their dependencies, usually to tex-bin-latex and a few 
tex-* packages.
