Using node-red-contrib-ibm-db2 in Cirrus

[glaoup]

Hi,
I'm currently moving a node-red app into cirrus hybrid cloud but facing problems with the nodes.
node-red-contrib-ibm-db2
I'm getting the following error while going through this nodes in the app log:

[error] [Db2 in:d4ad45c1.3a0e1] Error: Error loading shared library libcrypt.so.1: No such file or directory (needed by /usr/src/node-red/node_modules/ibm_db/build/Release/../../installer/clidriver/lib/libdb2.so.1)

Any idea what the pb is ?
Thanks
