minor build problem

I'm trying to build from the latest SVN sources on Mac OS X 10.4.3
and I seem to be having a problem making the documentation.

When I do make install, i get the following:

(sly at gigondas):~/src/R/r-devel/build-f95$ make install
make[1]: Nothing to be done for `front-matter'.
SVN-REVISION is unchanged
make[1]: Nothing to be done for `install'.
make[1]: Nothing to be done for `install'.
installing doc ...
/sw/bin/install: cannot stat `R.1': No such file or directory
make[1]: *** [install-man] Error 1
make: *** [install] Error 1

which is due to the fact that R.1 doesn't exist. When I try to make R.
1 by going into docs and doing make svnonly, I get:

(sly at gigondas):~/src/R/r-devel/build-f95/doc$ make svnonly
make[1]: `R.fe' is up to date.
help2man: can't get `--version' info from ../src/scripts/R.fe


When I try to run help2man manually I get:

(sly at gigondas):~/src/R/r-devel/build-f95/doc$ perl  ../../R/tools/
help2man.pl --include=../../R/doc/R.aux --no-info --output=R.1 --
name="a language for data analysis and graphics" ../src/scripts/R.fe
help2man: can't get `--version' info from ../src/scripts/R.fe


If I try to get the version info from ../src/scripts/R.fe directly, I
get:

(sly at gigondas):~/src/R/r-devel/build-f95/doc$ ../src/scripts/R.fe --
version

So that seems to work. There must be some problem parsing this
output. Does have an idea why help2man is failing here?

Thanks,
