I didn't mean "overriding the env is bad". I mean:
-> can we directly add ENVs for users?
-> how about doing this in wrapper script:
sed -i -e "$a\$(cat /usr/share/.../example/profile)" .bashrc
-> very bad.
Then can ENVs be handled automatically?
Then there are 2 things to convey to linuxbrew-wrapper users:
* linuxbrew packaging bug is not debian bug but upstream bug,
report linuxbrew bug at upstream github.
* there's a example profile located at
/usr/share/doc/linuxbrew-wrapper/examples/profile
and one can simply source it in bashrc/zshrc for the basic
linuxbrew utilization. If user installed some libs with
linuxbrew, he/she needs to handle BREW_LIB BREW_INCLUDE
LD_LIBRARY_PATH ...etc ENVs.
And I'm going to state them
* before invoking upstream install script
* in the manpage which is to be added.
Is there better way to tell the 2 points to users ?
* postinst ? *.News ?

LD_LIBRARY_PATH / RPATH:
IMHO LD_LIBRARY_PATH is better, since rpath is a problem
on Debian packaging and RPATH info is embedded into ELFs.

I think so. however
currently this package is not ready to get public attention.
At lease I need to compose a manpage to state the main idea
of this package.

I'm glad to hear that.

OK and thank you :-)
