Can't find proj

[robe]

I noticed winnies and bessies failing on 2,4, 2.5 and 3.0

with notice

On bessie

00:52:01 checking for shared library run path origin... /bin/sh: cannot open build-aux/config.rpath: No such file or directory

00:52:02 configure: error: could not find proj_api.h - you may need to specify the directory of a PROJ.4 installation using --with-projdir
00:52:02 *** Error code 1
00:52:02 

On winnie

Using user-specified proj directory: /projects/proj/rel-4.9.3w64gcc48
checking for proj_api.h... no
configure: error: could not find proj_api.h - you may need to specify the directory of a PROJ.4 installation using --with-projdir

Seems to be a result of commit r17109 (for 2.5) and related commits for 3.0, 2.4 ( r17110 ), and 2.3

I should note the thing that both winnie and the bessies have in common is in the configure scripts for both I set the —with-projdir configure switch. I think the other bots use their default proj install location.

So I suspect this switch might be broken.
