Thank you for reporting the problem!

Seems like a regular library location problem. (libelektratools has no special treatment, it is linked against kdb in the regular way. See ldd.) Libraries use LD_LIBRARY_PATH (might be different on Mac OS X) and not PATH. Please try to set this variable additionally.

Alternatively, you can try to follow the Troubleshooting guide in doc/INSTALL.md for a permanent fix.

Please report if this did not help.

Setting LD_LIBRARY_PATH seems to solve the problem. Thank you!
