ifneq ($(filter openssl,$(PACKAGES)),) ... endif I think. I would not recommend this. This will break if you switch collections without rebuilding everything. Also, you need to depend on openssl to make sure the file is already available. > 2) Someone™ adapts the openssl package to make it possible to choose > between installing the generic openssl.conf or her own copy from > projectroot. install_alternative should looks in pkgdir if nothing is found in projectroot etc. > 3) The third even more elegant solution I missed. Create a separate package that selects openssl and is enabled/disabled with it on the collectionconfig.
