problems with make

[Adriano Holanda <adriano at papaleguas dot fmrp dot usp dot br>]

My system is: Solaris 7 (SPARC)

I have installed binaries gcc in my machine, but some tasks it doesn't
make, like install some perl modules e some programs. So i decided install
the source gcc-2.95.2 and when I run make, this happened:

//final of the make output

  /usr/local/gcc-2.95.2/libiberty/vfork.c -o pic/vfork.o
gcc -c -DHAVE_CONFIG_H -g -O2 -I.
-I/usr/local/gcc-2.95.2/libiberty/../include
/usr/local/gcc-2.95.2/libiberty/vfork.c
rm -f libiberty.a
ar rc libiberty.a \

make[1]: *** [libiberty.a] Error 127
make[1]: Leaving directory `/usr/local/gcc-2.95.2/obj/libiberty'
make: *** [all-libiberty] Error 2

How can I install gcc 2.95.2 source without this error?

Thanks,

Adriano.
