[LAU] Problem Building Qjackctl-0.3.5

[David Baron]

qjackctlSetupForm.cpp:(.text+0x573f): undefined reference to `Pa_Initialize'
qjackctlSetupForm.cpp:(.text+0x575b): undefined reference to 
`Pa_GetHostApiCount'
qjackctlSetupForm.cpp:(.text+0x57f5): undefined reference to 
`Pa_GetHostApiInfo'
qjackctlSetupForm.cpp:(.text+0x589b): undefined reference to 
`Pa_GetDeviceCount'
qjackctlSetupForm.cpp:(.text+0x5a0c): undefined reference to 
`Pa_GetDeviceInfo'
qjackctlSetupForm.cpp:(.text+0x5b1a): undefined reference to `Pa_Terminate'

This can sometimes be fixed by moving -L/usr/lib or such but the link 
statement looks OK. Which library has these?
