Hi,
I emailed the list about a problem with the configure script for 5.0.3.
I have the latest Mesa library(6.0 something) and when I run the configure script I get the message that it can't find the openGL library. In particular, it can't
find glBegin. I checked libGL.so.1 and it does have glBegin (using nm -d the/library | grep glBegin). I took Glynn's advice and looked at the config.log and this is what
the last couple of lines were:

I don't understand what is the problem accept that the configure
script isn't finding the libGL.so.1. Does "confdefs.h" have anything to do with my
problem or is the latest Mesa library too new? Should I go for an older version of Mesa?

1. There needs to be a file (or a symlink to one) called "libGL.so",
without any trailing version number. If you installed Mesa from a
package (e.g. RPM), you may need to install the corresponding
development package (on RedHat it's called "Mesa-devel").
2. Is libGL.so in /usr/local/lib? If so, you need to add the switch:
