texlive-20110705 が出ている。minskim 先生に聞いたところ、 texlive 関係は結構独立だということだったので kpathsea だけを更新して見た。
しかし、さっそく

t-105@makoto 11:39:16/110725(..hoge-work/work)% make
mf '\mode=canonex; input ascgrp.mf'
warning: kpathsea: configuration file texmf.cnf not found in
these directories: /nonesuch.
This is METAFONT, Version 2.718281 (Web2C 2010)

kpathsea: Running mktexfmt mf.base
warning: kpathsea: configuration file texmf.cnf not found in
these directories: /nonesuch.
/usr/pkg/bin/mktexfmt: /texconfig/tcfmgr: not found
fmtutil: config file `fmtutil.cnf' not found.
I can't find the base file `mf.base'!
*** Error code 1

と言われてしまう。mktexlsr としても、

t-105@makoto 11:40:48/110725(..hoge-work/work)% sudo mktexlsr  
warning: kpathsea: configuration file texmf.cnf not found in
these directories: /nonesuch.
mktexlsr: Done.

となるので、戻して見た。

t-105@makoto 11:40:55/110725(..hoge-work/work)% \
sudo pkg_delete kpathsea
Package `kpathsea-6.0.0nb3' is still required by other packages:
        xdvik-22.84.16nb2
t-105@makoto 11:41:26/110725(..hoge-work/work)% sudo pkg_delete -f kpathsea
Package `kpathsea-6.0.0nb3' is still required by other packages:

これで元のように使えるようになった。
