I just built the Globus Toolkit on Solaris 10 / x86 (AMD Opteron). Here are the steps I went thru if these can be useful to anyone:

From the Download site, pick up the source: gt4.0.3-all-source-installer.tar bundle.

Make sure you have GNU tar and GNU make (I did not have them by default and installed these in /usr/local/bin)

As root, create the directory /usr/local/globus.4.0.3

Create a globus user, as this user here are the environment variables I have:

> printenv
HZ=
SHELL=/bin/bash
TERM=xterm
LC_ALL=C
MAIL=/var/mail/globus
PATH=/usr/local/bin:/usr/bin:/usr/sfw/bin:/usr/dist/share/devpro/5.x-i386/bin:/usr/ccs/bin:/usr/dist/exe
PWD=/etc/grid-security
LANG=C
TZ=US/Mountain
SHLVL=2
HOME=/users/globus
LOGNAME=globus
LC_CTYPE=C
_=/usr/bin/tcsh
HOSTTYPE=i86pc
VENDOR=sun
OSTYPE=solaris
MACHTYPE=i386
USER=globus
GROUP=other
HOST=myhost
GPT_LOCATION=/usr/local/globus-4.0.3
CC=/usr/dist/share/devpro/5.x-i386/bin/cc
GLOBUS_LOCATION=/usr/local/globus-4.0.3
GCC=/usr/sfw/bin/gcc

Run:

 ./configure --prefix=$GLOBUS_LOCATION --with-flavor=gcc32dbg

Then:

make

I ran into couple of problems. Initially did not have ar and pod2man in my path. So, I corrected my PATH by adding:

/usr/ccs/bin:/usr/dist/exe

Then, I ran into this problem:

file:/tmp/testgt/gt4.0.3-all-source-installer/source-trees/wsrf/java/core/source/build.xml:211: Compile failed; see the compiler error output for details.

due to the fact I uses a JDK1.5 compiler and enum is a reserved word used in:

import org.apache.axus.enum.Scope;

I edited the build file to add the -source 1.4 option such as:

source="1.4"

Then, I waited and waited and waited.... Eventually:

echo "Your build completed successfully.  Please run make install."
Your build completed successfully.  Please run make install.

Then:

> make install
/usr/local/globus-4.0.3/sbin/gpt-postinstall

I then try to run setup-simple-ca as the globus user:

> $GLOBUS_LOCATION/setup/globus/setup-simple-ca

Got this error:

creating CA config package... /usr/local/globus-4.0.3/setup/globus/setup-simple-ca: GLOBUS_LOCATION=/usr/local/globus-4.0.3: is not an identifier

So changed

#! /bin/sh

to

#! /bin/bash

Got this error:

creating CA config package...
ERROR: Unable to configure the simple_ca 9a7cd758 setup package

Corrected GPT_LOCATION such as:

setenv GPT_LOCATION /usr/local/globus-4.0.3

Then ran as root:

>  $GLOBUS_LOCATION/setup/globus_simple_ca_9a7cd758_setup/setup-gsi -default
>  $GLOBUS_LOCATION/bin/grid-cert-request -host myhost.central.sun.com
