when i configure GDAL like this:
./configure  --prefix=/usr/pkg  
--with-libgrass=/usr/pkg  \
--with-tiff=internal  \ 
--with-gif=internal  \
--with-png=internal  \
--with-jpeg=internal  \
--with-libz=internal  \
--without-netcdf  \ 
--without-jasper  \
--without-python \

building GDAL+ECW is OK  but i obtain this:

pmg4:~/Desktop/GDAL_conversion_folder/sample_geotiff pb$ \
gdal_translate --debug ON   -of ECW -co "TARGET=90" -co "DATUM=WGS84" -co
"PROJ=NUTM10"  sample_geotiff_bigEndian.tif   sample.ECW
GDAL: GDALOpen(sample_geotiff_bigEndian.tif, this=0x5a09de0) succeeds as
Input file size is 655, 655
ERROR 1: libgrass: MAPSET is not set
Abort trap
