Sorry Even, but it still fails

gdaltransform -s_srs EPSG:4326 -t_srs "+proj=bonne +lat_0=1 +wktext"
ERROR 6: Failed to initialize PROJ.4 with `+proj=bonne +lat_0=1 +wktext'.

And I'm facing some other issues with the +wktext.

This GMT using proj.4 via GDAL, and it works.

grdproject lixo.grd -J+proj=sinu -Glixo2.grd

but adding +wktext makes it fail in GDAL

grdproject lixo.grd -J"+proj=sinu +wktext" -Glixo2.grd
ERROR 6: Failed to initialize PROJ.4 with `+proj=sinu +wktext'
