Solaris Client Install

[mv652 (at) softhome.net]

This is my second 'main' question that I have split. 

I am trying to setup a Xymon 4.3.0 client on a Solaris 10 system, but it 
fails during compiling after I run 'make'. 

The main problem seems to be with "ld", but I'd appreciate your opinions if 
I have something major missing or misconfigured. 



The "configure client" before 'make' runs ok, except for an error message 
after "Checking for Large File Support":
Checking for Large File Support ...
ERROR: LFS support check failed for standard file support 

Checking for clock_gettime() requiring librt ...
clock_gettime() requires librt 



I am defintiely using GNU make:
# /usr/local/bin/make -v
GNU Make 3.81 

gcc was already pre-installed:
$ /usr/local/bin/gcc -v
Reading specs from /usr/local/lib/gcc/sparc-sun-solaris2.10/3.4.6/specs
Configured with: ../configure --with-as=/usr/ccs/bin/as 
--with-ld=/usr/ccs/bin/ld --enable-shared --enable-languages=c,c++,f77
Thread model: posix
gcc version 3.4.6 


The error during 'make' is:
... <output truncated>
config.h created

Advice or points in the right direction appreciated..
