1.8.1 config fails, but gmp passed its tests.

[Hugh Sasse]

Configuring guile-1.8.1 on Sun Sparc Solaris2.9 fails thusly:

checking whether sethostname is declared... no
checking for library containing crypt... none required
checking for __gmpz_init in -lgmp... no
configure: error: GNU MP not found, see README
You have mail in /var/mail/hgs

I have installed gmp-4.2.1 on the system, and it passed all its tests.

I have seen 
http://www.archivum.info/address@hidden/2006-03/msg00024.html

and subsequent messages: and though there is no response about 
compiling the C program to debug this I get:

bash-2.05$ cat foo.c
#include <gmp.h>
int
main ()
{
  mpz_import (0, 0, 0, 0, 0, 0, 0);
  return 0;
}

bash-2.05$ gcc -o foo -g -O2 foo.c -lgmp -lcrypt -lm -lltdl

And I have

with ld built after that GCC, formerly from binutils-2.16, which failed
also.

What else should I tell you about?  As the cited thread states, there
is nothing useful stated in config.log about gmp.
