Configure is failing on a 4.7-STABLE  FreeBSD machine. 

It seems tarnge that it' trying to build amplot ayway, as I have 
--without-server passed as an argument to configure in my script I use to
run it.

Here's how it's failing:

checking for xsltproc... /usr/local/bin/xsltproc
configure: creating ./config.status
config.status: creating amplot/amcat.awk
./config.status: line 785: : cannot execute [Is a directory]
config.status: creating amplot/amplot.sh
./config.status: line 785: : cannot execute [Is a directory]
config.status: creating amplot/Makefile
./config.status: line 785: : cannot execute [Is a directory]
