Error in building 2.5.0p2 on Solaris 9

Greetings all;

I'm attempting to compile and install amanda-2.5.0p2 on a 2-way Sunfire V210 running Solaris 9 w/ 2gb RAM. Compiler is gcc, v3.4.2, linker is Sun's supplied /usr/ccs/bin/ld. Worthy of note is that this same package configured and compiled flawlessly on a 2-way Dell 1850 server running RHES 3.0.

Here are my configure parameters:

./configure --prefix=/usr/local/prdamanda --with-index-server=amanda2 --with-user=prdamanda --with-group=disk --with-config=prodbackup --with-tmpdir=/tmp/prdamanda --with-gnutar=/usr/local/bin/tar

========================================
The configure runs to completion with no warnings or errors save one, GNUplot not being installed. No biggie there. The "make" produces the following warnings as it proceeds through the building the code:

=============================================
Despite the warnings, everything goes smoothly until the build process reaches the building the "man" pages section, when it errors out completely:

==================================

Not sure where to go from here, I've never seen this when building amanda from source before. If I've missed supplying any necessary information to help trouble-shoot, please let me know. Any help/guidance appreciated. Thanks.
