Yes I agree.  Debian has the luxury of using GDAL by default, which is  
the only sane way this should go.  But I can't make GDAL a hard  
requirement for libLAS.  Another complication is likely to arise when  
GDAL in turn starts linking against libLAS, but we'll burn that bridge  
when we need to :)

liblas-config is one place you can get this information, but it  
doesn't help the person who's coding to decide how to treat the srs.

Thanks for your input.... still chewing on this chewy one.
