here is the cricial part of the logs:

Checking for header occi.h : Missing include files for OCI

To fix it, you need to set OCI_INCLUDE_DIR and OCI_LIB_DIR env variables

Assuming that oracle client and sdk are installed in /opt/instantclient

$ export OCI_INCLUDE_DIR=/opt/instantclient/sdk/include/ 
$ export OCI_LIB_DIR=/opt/instantclient

Then just install the module.
