How to tell portage to ignore MD5 check of a package?

[xenon]

I am in need of applying a small patch to the sources of a package, but I guess this will break the MD5 hash check and the app won't be emerged. Is there a way to tell portage to ignore the MD5 check or should I just compile and install it manually?

Thanks.

in this case you can create your own md5 hash using the ebuild command. e.g.: ebuild digest /path/to/package. i suggest using the portage overlay facility for this. e.g. if you want to create your own version of an existing package (i.e. app-misc/multimon) create the following directory using the following command:

mkdir -p /usr/local/portage/app-misc/multimon/files

now edit /etc/make.conf and add PORTDIR_OVERLAY="/usr/local/portage" to it (there is already an example in the file which you just need to uncomment). now copy the original ebuild (e.g. /usr/portage/app-misc/multimon/multimon-1.0.ebuild) to /usr/local/portage/app-misc/multimon and edit the file as you need. put your and the original patches from /usr/portage/app-misc/multimon/files (multimon doesnt have any) into /usr/local/portage/app-misc/multimon/files.

now run ebuild digest /usr/local/portage/app-misc/multimon/multimon-1.0.ebuild and a new digest-multimon-1.0 file will be created in /usr/local/portage/app-misc/multimon/files to reflect your changes.

to install your package now just run your usual emerge command (e.g. emerge app-misc/multimon - emerge will use your version instead of the one under /usr/portage).

Thanks a lot for the information. I'll try it soon and post the results.

The best I get when trying to finally emerge the app is:

Well, I tried the elegant way and failed, so I did it the dirty way.

I put my repacked sources tarball in /usr/portage/distfiles, and edited the digest file to reflect the new MD5 hash generated by the ebuild digest command. It worked.

Thanks for your help.
