build fail with makeinfo missing

[M R Swami Reddy]

Hello,

During the build of binutils-2.18-50/bfd, the below issue seen:
==
WARNING: `makeinfo' is missing on your system.  You should only need it if
          you modified a `.texi' or `.texinfo' file, or any other file
          indirectly affecting the aspect of the manual.  The spurious
          call might also be the consequence of using a buggy `make' (AIX,
          DU, IRIX).  You might want to install the `Texinfo' package or
          the `GNU make' package.  Grab either from any GNU archive site.
make[3]: *** [bfd.info] Error 1
====

I have the "makeinfo" in path.
 > makeinfo --version
   makeinfo (GNU texinfo) 4.5

Could you please advise, what could be wrong and how it can be solved?

Thanks
Swami
