I fully agree with Bruno. We could also check for an existing wget in bootstrap.conf and set SKIP_PO=1 if not found. While it 'just works' it also disguises the real problem and the user might get something unexpected (non-internationalized wget).

Alternatively, you could change the build system so that - 'make' recurses into the 'po/' directory only after 'src/', - Fetching the PO files is done through po/Makefile, not bootstrap, - po/Makefile uses src/wget, if not cross-compiling, instead of wget from $PATH.

How about a --disable-translation configure option similar to --disable-docs. That should get you over the bootsrap hurdle. But it assumes you have a adequate Unistring and OpenSSL. (From experience with some older systems and ransomware systems, I've found the minimum components needed to build Wget are Unistring and OpenSSL: https://github.com/noloader/Build-Scripts/tree/master/bootstrap).

argp-version-etc broken on OpenIndiana
Hello there! I just tried to build Inetutils with a freshly updated Gnulib source, doing so for the first time in perhaps three weeks on my regular OpenIndiana system with gcc-4.3.3. To my surprice Gnulib source wreeks havoc on the file `argp-version-etc'. A build log is attached. My guess is that `ctype_iso.h' is the point of failure, but also `version-etc.h' afronts as a strong candidate.

Re: argp-version-etc broken on OpenIndiana
Hello again, looking at Hydra/Nixos, the autobuild system failed due to commit c08f85d made three days ago to gnulib, and it has not recovered since then. This seems to correspond to my report. Regards, Mats E Andersson [1] http://hydra.nixos.org/jobset/gnu/inetutils-master
Re: argp-version-etc broken on OpenIndiana
Ah, I missed a use of that attribute within Gnulib when installing the recent changes for __has_attribute. I installed the attached patch to fix it, and the followup two patches (also attached) to fix some style nits I noticed while fixing the bug.
