Possible glitch in Autoconf 2.64?

[Bob Friesenhahn]

I have this report from a GraphicsMagick user encountered under 
Apple's OS-X:

$ ./configure
configure: error: cannot find install-sh, install.sh, or shtool in ltdl/config 
"."/ltdl/config

Note that the above formatting is exactly as provided.

He only gets this error with GraphicsMagick which has been updated to 
Autoconf 2.64.  I have not been able to reproduce it.

Has anyone else seen this issue?

Thanks,

Bob
