[Mapserver-dev] Configure error causes GD2.0.12 not found error

[R. Piepul]

I believe the LIBS list in the configure script needs to include
libiconv (-liconv). Without it, configure incorrectly reports that GD
2.0.12 cannot be found and then exits. I would like someone to confirm
this, since I'm new to ms and this problem may be due to some other
issues on my system.

I'm trying to build mapserver cvs as of Sunday, 22 June. I have also
run into this same problem with ms3.6.6.

The configure script indicates that it cannot find GD >= 2.0.12. But
I have installed GD2.0.15. The config.log file indicates undefined
references to iconv_open,iconv_close,iconv in the check for GD.
The problem was fixed (for me) after substituting all occurrences of
   "-lgd"  with "-lgd -liconv"


If you want my patch I will post it or file a bug report. However, I'm
not sure if this is the correct way to fix it.
More details below.
Thanks,
Rob
