The relevant error in the log seems to be

:info:build xsltproc --novalid http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl dia.dbk >dia.1
:info:build http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl:1: parser error : Document is empty

Are you able to access ​http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl in your web browser?

[martinezino@…]

yes, i am able to access that URI:

$ curl -I http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
HTTP/1.1 200 OK ...

[ryandesign (Ryan Carsten Schmidt)]

Ok. And if you sudo port clean dia and try again, does it fail again?

[martinezino@…]

sudo port clean dia; sudo port install dia

[jmroot (Joshua Root)]

Shouldn't it be using a local copy of docbook-xsl rather than downloading stuff in the build phase?

[martinezino@…]

that was it:

$ sudo port install docbook-xsl
...
$ sudo port install dia
...
--->  Installing dia @0.97.2_3
--->  Activating dia @0.97.2_3

conclusion: missing docbook-xsl dependences

thank you!

dia: add dependency and fix help

Add docbook-xsl dependency - force use of local docbook.xsl
Force creation of html help - use open instead of xdg-open

Some patches come from Debian and master branch of dia
