All,
I tried to build wireshark 0.99.6 on several platforms and I discovered 
several problems I'm reporting on this email.
I haven't been following up the mailing list, so I don't know if they 
are known problems or not. Anyway:
[1] When building a rpm package, the rpm build fails because of a 
warning that is treated as error (when it should not be!).
The problem is reported in: wiretap/file_access.c (line 993) (the 
warning is about passing a 'const' pointer to gzwrite that is declared 
to take a non-const pointer).
As workaround, simply change the RPM SPEC file under 
packaging/rpm/SPEC/wireshark.spec.in (or, if you have already run the 
configure, change the packaging/rpm/SPEC/wireshark.spec) to have 
--disable-warnings-as-errors in the CFLAGS.
The correct fix would be to understand why the rpm build uses the 
-Werror flag even if not requested...
[2] The RPM build still fail because apparently the man pages are now 
installed under $PREFIX/share/man instead of $PREFIX/man.
The workaround is, again, to change the SPEC file (same as above), 
replacing the line:
%prefix/man/*/*
into:
%prefix/share/man/*/*
(in %files section)
Again, the correct action would be to understand why the man pages are 
installed under '$PREFIX/share' now and perhaps move it back the way it 
was before.
[3] On RedHat Enterprise 3, CentOS 3, and RedHat 9 the build fails 
because the file:
gtk/export-object.c
uses some functions that are available only on GTK 2.4 and above.
The correct fix is to #ifdef those sections to use the new API (GTK 
2.4>) only if gtk+2.4 is available, or use the old API for older gtk.
Attached you can find the .diff file for this.
