Code listing for beginning on lines 224, 382 where 'make' fails in the "RunDecoder" function of
libmpeg2.c:

<snippet>
[Line 224] mpeg2_pts( p_dec->p_mpeg2dec,
                               (uint32_t)p_dec->p_pes->i_pts );
                    p_dec->i_previous_pts = p_dec->i_current_pts;
[Line 226]                 p_dec->i_current_pts = p_dec->p_pes->i_pts;

<snippet>
[Line 382] (p_dec->p_info->current_picture->flags & PIC_FLAG_PTS) ?
                    ( (p_dec->p_info->current_picture->pts ==
                                (uint32_t)p_dec->i_current_pts) ?
[Line 385]                            p_dec->i_current_pts : p_dec->i_previous_pts ) : 0


Steps taken to rectify:
1. Reviewed the source file /var/tmp/portage/vlc-0.6.2/modules/codec/libmpeg2.c to identify the line number(s) where 'make' fails.
2. 'make' fails on line 224, then 382 and 383 with the errors identified in the ouput above.
3. Individually emerged 'libmpeg2-0.4.0b', then 'ffmpeg-0.4.7'; both 'emerged' with no errors.
4. cd /var/tmp/portage/vlc-0.6.2
5. make distclean
6. Executed a manual './configure' - no problems here
7. Executed "make"; 'make' fails with the same error as above...
8. emerged MPlayer as a test...1) Does it emerge cleanly? YES; 2) If yes, then will it play files? YES. No problem, even with extremely large files, other than the fact that this computer doesn't have the hardware to play files adequately under Linux.(it is a "test-box" using older hardware after-all...)
9. Checked the 'Include' files, including /var/tmp/portage/work/vlc-0.6.2/modules/codec/libmpeg2.c for any reference to 'mpeg2_pts'; none found.
10. Not being a programmer, will assume that the function 'mpeg2_pts' cannot be found in any Include file, and therefore the error.
11. Hopefully, some of this will help those more competent than I in tracking down the problem.
