Uhm, I bet this is something quite obvious, but I fail to see it.
Any help greatly appreciated. I tried a make build (with the new
toolchain settings in mk.conf) which fails. I tried both make build
and build.sh. I set my variables after I read the BUILDING file ...
I do not see anything related to my problem in UPDATING (and I should
not have to look there with the new toolchain if I got that right ?)

Well, here's the tail of my problem:

This occurred with a make build. build.sh fails at the same point.
Uhm yes, I'm clueless.

K, here's my mk.conf parts for toolchain:

USE_NEW_TOOLCHAIN=yes
USETOOLS=yes
TOOLDIR=/usr/tools
MKTOOLS=always
DESTDIR=/usr/newroot
MKCATPAGES=yes
MKCRYPTO=yes
MKDOC=yes
MKINFO=yes
MKLINT=yes
MKMAN=yes
MKNLS=yes
MKOBJ=yes
MKPIC=yes
MKPICINSTALL=yes
MKPROFILE=no
MKSHARE=yes
UPDATE=no
MKOBJDIRS=yes
RELEASEDIR=/usr/release
NOCLEANDIR=yes

Well, TIA.
