linc-0.13 fails compiling

[Chris Chabot <chabotc reviewboard com>]

While trying to compile (rpm -ta) linc-0.13, it errors on the well known 
'missing index.sgml' in the make install part. This is with the gtk-doc 
& intltools which are included in the same gnome-2.0-alpha (staging)

Complete output:

if test "$installfiles" = './html/*.html'; \
then echo '-- Nothing to install' ; \
else \
 for i in $installfiles; do \
   echo '-- Installing '$i ; \
   /usr/bin/install -c -m 644 $i 
/var/tmp/linc-0.1.13-root/usr/share/gtk-doc/html/linc; \
 done; \
 echo '-- Installing ./html/index.sgml' ; \
 /usr/bin/install -c -m 644 ./html/index.sgml 
/var/tmp/linc-0.1.13-root/usr/share/gtk-doc/html/linc; \
