[R] Problem in installatin under Unix

[Mohamed KAABI]

Hi all,
I wanted to install R under a sunOs machine, so I launched the configuration with the following command:

"./configure --prefix /sw/gnu/R/R-2.1.0/sun/ --with-readline=no"

The rsult of this configuration seemed good
"
R is now configured for sparc-sun-solaris2.8

  Source directory:          .
  Installation directory:    /sw/gnu/R/R-2.1.0/sun/

  C compiler:                gcc  -g -O2
  C++ compiler:              g++  -g -O2
  Fortran compiler:          g77  -g -O2

  Interfaces supported:      X11, tcltk
  External libraries:
  Additional capabilities:   PNG, JPEG, MBCS, NLS
  Options enabled:           R profiling

  Recommended packages:      yes

configure: WARNING: you cannot build info or html versions of the R manuals
"

Then I launched make but I get this error
