Would this build error happen eventually on non-nix builds? Would there be an adaptation that we would need to apply to all of our other builds for this?

This issue is caused by removal of default support of http in libxml2 . GRASS must be using it somewhere.

@neteler is there something to do about this?

I wonder how to look for it:

ag libxml2 
mswindows/osgeo4w/liblas-config
46:LIBXML2_INCLUDE_DIR=""
47:if test -n "$LIBXML2_INCLUDE_DIR" ; then 
48:    INCLUDES="$INCLUDES -I$LIBXML2_INCLUDE_DIR"
50:LIBXML2_LIBRARIES=""
51:if test -n "$LIBXML2_LIBRARIES" ; then 
52:    LIBS="$LIBS $LIBXML2_LIBRARIES"

mswindows/crosscompile.sh
302:	libxml2-2.dll \

package.nix
23:, libxml2
82:    libxml2

In my view liblas isn't relevant at all any more (since we support PDAL) and could be dropped.

[echoix]

Is it a transitive dependency then?

[hellik]

PDAL doesn't work winGRASS so far; IIRC some c++ compiling/linking issues.

[hellik]

That's may be the reason for liblas.
