[Sarawut Ninsawat]

Dear All,

I have a problem with pgdijkstra

I try to install dijkstra.sql with

"psql -d demo_ins -f dijkstra.sql "

and I got this error

ERROR:  could not access file "MODULE_PATHNAME": No such file or
directory

but

"psql -d demo_ins -f dijkstra_postgis.sql "

is no problem.

I use Linux mandriva with PostgreSQL 8.04 and latest postGIS

Any idea about this error.
