Problems running version 4.10.0 rc1

[José Vicente Higon]

Hello,
I've compiled mapserver 4.10.0 rc1 with gdal 1.3.2 on linux and I've 
realized two problems:
1. If compile with geos I get an error like this:
mapgeos.c:34:20: geos_c.h: File not found

2. I can't get get an image with output format trought GDAL like "tiff  
32 bit float". Mapserver returns a 500 html code (mapserver crashes).
The outputformat definition is like this :

OUTPUTFORMAT
  NAME GTiffFloat
  DRIVER "GDAL/GTiff"
  MIMETYPE "image/tiff; mode=float32"
  IMAGEMODE FLOAT32
  EXTENSION "tif"
END

Someone can help me?

Thanks in advance
