Some users will emerge multiple versions of autoconf without cleaning up previous versions (for example, have 2.57a and 2.58 installed simultaneously). The problem with this is that /usr/bin/autoconf-2.xx calls /usr/bin/autom4te, which should call the appropriate version, but this scenario could happen: /usr/bin/autoconf-2.57a gets called, which in turn called /usr/bin/autom4te (from the AUTOM4TE variable), which determines that /usr/bin/autom4te-2.58 needs to be called. This causes a versioning conflict. Instead, we should add a line in /usr/bin/autoconf which sets the AUTOM4TE environment variable to set the appropriate autom4te version when using autoconf. That is, in /usr/bin/autoconf-2.58, set AUTOM4TE='/usr/bin/autom4te-2.58' That way, the proper autom4te gets called from autoconf. Reproducible: Always Steps to Reproduce: emerge two simultaneous versions of autoconf without cleaning the older one out. This is reasonable, so that software designers can test their auto scripts on multiple versions. Actual Results: programs calling autoconf specific versions fail because autom4te may run a different conflicting version.
