[xml] OS X install problem?

[Paul Kelly <pjkelly5 home com>]

Hi, first posting here. I've searched the archives but can't find an answer.

I've installed 2.3.11 to avoid OS X problems with later 
versions--someone said anything past 13 won't work and was warned off 
13 itself by someone on the Axkit (xml app server) list--but I'm 
uneasy with the results. Here are the last few lines of the 'make 
install' report:

/usr/bin/install -c -m 0644 ./html/*.html /usr/local/doc/libxml2-2.3.11/html
/usr/bin/install -c -m 0644 ./html/index.sgml 
/usr/local/doc/libxml2-2.3.11/html
(cd ; gtkdoc-fixxref --module=libxml --html-dir=/usr/local/doc)
zsh: command not found: gtkdoc-fixxref
make[2]: [install-data-local] Error 1 (ignored)
Making install in example
make[2]: Nothing to be done for `install-exec-am'.
make[2]: Nothing to be done for `install-data-am'.

Should I be concerned? I mean, it passed 'make test' with flying colours.

thanks
