[Discuss-gnuradio] Pybombs Prefix and Modtool

I think I've narrowed down what I and some colleagues of mine have been experiencing enough to explain it and hopefully get a solution.

When I installed gr using the new pybombs, I specified a custom prefix location (on several computers). It seems that later on, when I create an OOT module using modtool, GRC does not interact properly with these OOT modules, for some reason unknown to me that I'm assuming is related to this prefix. The only workaround I know to get OOT modules to show up in GRC now is to add each OOT module directory path to the GRC_BLOCKS_PATH env variable. This causes XML parser errors to be reported everytime I open GRC, and slows it down.

So my question is this:

With the old pybombs, I always used the default prefix and thereafter modtool always worked. After sudo make install and sudo ldconfig, my OOT blocks showed up in GRC. Since now I chose a custom prefix, is there an additional step I am supposed to take when making OOT blocks?

Summary: Installed GR using new Pybombs in custom prefix. Installing OOT module custom blocks does not work without editing GRC_BLOCKS_PATH variable for each OOT path.
