OK, i think i see what is going on ..... either the wizard library 
libs/wizards, libkbase_wizard) is not being linked in, or the static 
constructors in it are not getting executed. As a result, the wizard controls 
are not registered, so when the new connection wizard executes, the 
list-databases control is missing. You can see this by ........

KBWizardCtrlReg::makeWizardCtrl: [WizFile]->[0x0
KBWizardCtrlReg::makeWizardCtrl: [DBType]->[0x0
KBWizardCtrlReg::makeWizardCtrl: [next]->[0x0
KBWizardCtrlReg::makeWizardCtrl: [ok]->[0x0
KBWizardCtrlReg::makeWizardCtrl: [DBList]->[0x0
KBWizardCtrlReg::makeWizardCtrl: [WizFile]->[0x0

and the wizard fails ....

executing wizard
leaving mr. _KBDialog::show()
KBWizardPage::compile: [next][
        local dbtype = page.ctrl("dbType") ;
print (dbtype.value() + "\n") ;
        if (dbtype.value() == "xbase") return "xbase" ; 
        return (dbtype.attr("flags") & 0x01) == 0 ? "database" : "host"
    ]
if_pageCtrl: not found: [dbType]


IIRC there is an issue on MAC OS/X to do with static constructors - rekall 
uses them quite a lot to dynamically register components (form+report 
controls, macro instructions, wizard controls. Have you tried designing a 
form and, if so, can you create any controls.

There was some code around a while back to do the registration without static 
constructors (for form/report controls) when we thought this might be a 
problem for the Windows build, if neccessary I could resurrect it into the 
2.3.x code base and do the same for macros and for wizard controls.

I'd suggest creating an admin.osx.kde3 directory, or some similar name, and 
modifying Makefile.cvs so you can do

make -f Makefile.cvs osx-kde

or suchlike, then there is no need to worry about breaking linux builds (at 
the cost of some duplication)

Having an OS/X version of Rekall is really great, I'm happy to provide all the 
help I can on this. If it would help, we can run an IRC channel on this
