>Description:
Installing pkgtools/pkg_install fails with

#     build  libfetch/libfetch.a
rm -f libfetch.a
ar cq libfetch.a `NM=nm lorder fetch.o common.o ftp.o http.o file.o | tsort -q`
ranlib libfetch.a
#    format  libfetch/fetch.html3
groff -Tlatin1 -mdoc2html fetch.3 > fetch.html3.tmp &&  mv fetch.html3.tmp 
fetch.html3
troff: fatal error: can't find macro file doc2html

I assume, pkg_install is not meant to be installed on NetBSD at all?

Build of pkg_install gets only triggered when updating using 
pkg_rolling-replace, and only by some packages (i.e. it seems some other 
packages install fine before pkg_install is tried). When using "pkg_chk -u" to 
update packages, pkg_install is not touched. 
>How-To-Repeat:
After the error first appeared, I removed all packages and cleared /usr/pkg. 
Then I installed all packages via "pkg_chk -a" (680 packages in total) without 
any problems. After the next CVS update, pkg_rolling-replace failed again in 
the way shown above.
