KDevelop 3.1.1 "Documentation" tab not coming up on Solaris

[Albert Chin]

I've built KDevelop 3.1.1 on RHEL 3.0/x86, Solaris 9/SPARC, and IRIX
6.5. On RHEL 3.0/x86, the "Documentation" tab next to the "Code
Snippets" tab is present. However, for the Solaris and IRIX builds, it
is not. The doxygen documentation was built for all three platforms
and lives in $prefix/doc/HTML/en/*-apidocs.

Where should I start looking?
