Tcl 8.5.15: package msgcat not found

Hello,

with the recent Tcl 8.5.15 update, I am having trouble using [clock
format]:

[root at www ~]# pkg query '%o %v' | grep tcl
lang/tcl85 8.5.15
[root at www ~]# tclsh8.5
% puts [clock format [clock seconds] -format {%Y-%m-%d}]
can't find package msgcat 1.4

The lang/tcl85 pkg was built on the same host using poudriere, the
options are set to build modules:
OPTIONS_FILE_SET+=MODULES

I can't figure out where the problem is, please advise.
