hey Mich there is some kind of re link/share issue with the new version of BFG if you try to up date it etc i keep getting this
./bfgminer: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory
and if you make it inside minera it's hit and miss it may make but still not work you might get a re link error which i went looking and found a fix that doesn't work,so, just a heads up you might get pounded with questions till i guess luke fixes whatever he did unless minera has to be adjusted now for the new version .i did compile it in the OPT folder and CP to the minera folder, didn't do any good i still get
./bfgminer: error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory
BFG 5.4.2 works fine stand a lone.
and using the custom folder same thing
/var/www/minera/minera-bin/custom/alchemist: error while loading shared libraries: libbase58.so.0: cannot open shared object file: No such file or directory
just a heads up .
thats an easy fix. after you do make, do sudo make install and sudo ldconfig
did that, for me i can't get 5.4.2 to work with minera 5.4.1 does . and i have 5.4.2 working fine stand a lone .
minera does the same thing just before it cp/copy's it to /var/www/minera/minera-bin with
make
sudo make install
sudo ldconfig
in the build_miner.sh file.
trying again with minera manually to see if that works and some times it won't compile at all inside minera but will any place else . just 5.4.2 all the other soft ware miners work fine.
This was more a heads up , your right i might be doing something wrong
.I guess it was me and don't enable --alchemist it seems that might cause issue with minea, it wasn't with 5.4.1 and minera, this time thu i deleted the minera folder and downloaded the master renamed it then copied it to right folder on my pi etc used the right build script, it worked .

last thought it might be related to your issue in the bfg thread with those stick miners, there from the same chip or alchemist chips and bfg 5.4.2 ,or luke fixed it, didn't tell us, not that he has to, he doesn't , guess we wait.
