Frank McQuillan commented on MADLIB-1068:
-----------------------------------------
We have observed in the past that even though there are occasional install
check failures, the installation is actually OK and MADlib works fine. This is
especially the case when the failures are intermittent and non-repeatable.
> madpack install-check fails on PostgreSQL 9.6.2 & Ubuntu 16.04.2

> I am installing MADlib from source and concerned about the errors *madpack
> ... install-check* reports. Here are the commands used:
> {code}
> apt install postgresql-server-dev-9.6
> apt install postgresql-plpython-9.6
> apt install cmake g++ libkrb5-dev m4 libboost-dev
> git clone https://github.com/apache/incubator-madlib
> cd incubator-madlib
> ./configure
> cd build/
> make
> make install
> src/bin/madpack -s madlib -c postgres/*@localhost/revit -p postgres install
> ...
> ...
> ...
> madpack.py : INFO : MADlib 1.10.0 installed successfully in MADLIB schema.
> {code}
> Next I run *madpack ... install-check* but it fails. Should I be concerned or
> is this possibly a bug? See attached log file:
> {code}
