R-beta: Problems during compilation of R for Solaris 2.6

[Dott. Nunzia Galdi]

Hello,
I am inexperienced in C program compilation and I receive the following
error during the compilation of R (version 0.61.2) for Solaris 2.6.
I have installed the gcc 2.8.0 version.

>> gcc  -o R.binary arithmetic.o  array.o  attrib.o  bind.o  builtin.o  character.o  >> coerce.o  colors.o  complex.o  context.o  cov.o  cum.o  dataframe.o  debug.o  >> deparse.o  deriv.o  dotcode.o  dstruct.o  duplicate.o  envir.o  errors.o  eval.o  >> format.o  fourier.o  iosupport.o  gram.o  list.o  logic.o  main.o  match.o  memory.o >> model.o  names.o  objects.o  optimize.o  options.o  par.o  paste.o plot.o  plot3d.o  >> plotmath.o  print.o  printarray.o  printvector.o  printutils.o  random.o  relop.o  >> saveload.o  scan.o  seq.o  sort.o  source.o  split.o  subassign.o  subscript.o  >> subset.o  summary.o  unique.o  util.o  version.o ../lib/libgraphics.a  >> ../lib/libunix.a  ../lib/libappl.a  ../lib/libmath.a -lSM -lICE -L/usr/openwin/lib >> -R/usr/openwin/lib -lX11 -lsocket  -lnsl -ldl -lreadline -ltermcap -lm

Could anyone suggest me something,
