Problem building math/R: texi2dvi needed but missing on your system

[Benjamin Stier]

Hello everybody,

I'm trying to build math/R. Compilation went fine, but when I try to 
'make install' I get the following error:

> ERROR: 'texi2dvi' needed but missing on your system.
> *** Error code 1
> 
> Stop in /usr/ports/math/R/work/R-2.13.1/doc/manual.
> *** Error code 1 (ignored)
> cd: can't cd to /usr/local/lib/R/lib
> *** Error code 2
> 
> Stop in /usr/ports/math/R.

I have a texi2dvi4a2ps binary as you can see here.

> # where texi2dvi4a2ps
> /usr/local/bin/texi2dvi4a2ps
> # pkg_info -W /usr/local/bin/texi2dvi4a2ps
> /usr/local/bin/texi2dvi4a2ps was installed by package a2ps-a4-4.13b_4

Has anyone else seen this problem before and can give me some tipps?

Kind Regards,

Benjamin
