Ubuntu build fails

[GoogleCodeExporter]

Reproduce the problem:
1. download source archive (libofa-0.9.3) :)
2. ./configure
3. make

I get a build error like this: 
make[3]: Entering directory `/libofa-0.9.3/lib'
if /bin/bash ../libtool --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I..
-I../include    -g -O2 -Wall -g -MT mainprint.lo -MD -MP -MF

    then mv -f ".deps/mainprint.Tpo" ".deps/mainprint.Plo"; else rm -f
".deps/mainprint.Tpo"; exit 1; fi

What version of the product are you using? On what operating system?
gcc (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7)
on Ubuntu 8.10

Please provide any additional information below.
The fix: add a "using __gnu_cxx::abs;" in JAMA/tnt_math_utils.h @ line 33;

After this the build works fine

I dont know of other solution then. I stopped working with libfoa a long time 
ago, as i didn't have the necessary time

Did you worked on the same domain after leaving libofa..??
Can you suggest me any other such library which can be used in lieu of 
libofa..??

I really know jack about it, but this makes it go on Slackware 13.37.0/gcc 
version 4.5.2.. I blew away examples, so no examples..
