Preferences: Libraries buttons grayed out

I've just had a reply from one of the developers (not had chance to test it yet):

I investigated the bug and found out, that this issue was caused by a
bug in vamp-plugin-sdk 2.5+repack0-1. I fixed the bug in vamp-plugin-sdk
2.5+repack0-1 and uploaded 2.5+repack0-2 to Debian unstable. Please
update the package and then you can build audacity again.


Long story:
$ pkg-config --libs vamp-hostsdk
returns the linker flags for this library. The faulty version of
vamp-plugin-sdk returns "[email protected]@ -lvamp-hostsdk -ldl". -L specifies a
library search directory and should be a existing path, but is @[email protected]
in this case. @[email protected] should have been replaced with /usr/lib (or
whatever you configured the library). libtool tries to determine the
absolute path of @[email protected], but obviously fails to do that.

I'm getting the same error on Jessie and I don't know what is causing it.
I'll post again if I find out anything. Please do likewise

I took the easy way out: I backed up everything and reinstalled my OS. Now it's working. I should note though that I installed Wheezy, then installed the Wheezy package Audacity, then updated my sources.list to Jessie.

vamp-plugin-sdk has now been updated in Jessie, so the problem "should" now be fixed. (I've not tested yet).

Just tested it. Audacity now builds on Debian testing (Jessie), though for a "production machine" I'd still recommend using Debian stable.
