On Fedora 25 with bullet physics 2.83, the makepanda-generated rpm cannot be installed (it appears ecause it hardwires a dependency to bullet 2.82):

[root@cyberman panda3d]# dnf install panda3d-1.10.0-1.x86_64.rpm
Last metadata expiration check: 0:03:40 ago on Tue Mar 14 14:53:48 2017.
Error: nothing provides libBulletCollision.so.2.82()(64bit) needed by panda3d-1.10.0-1.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages)
[root@cyberman panda3d]# locate libBulletCollision
/usr/lib64/libBulletCollision.so
/usr/lib64/libBulletCollision.so.2
/usr/lib64/libBulletCollision.so.2.83
[root@cyberman panda3d]#

Are you sure that Bullet wasn't upgraded after initially making your build? Does the problem still occur when uninstalling Panda, deleting the "built" directory and building from scratch?

If anyone stumbles across this and has the same problem, the following workaround works:

Create symlinks:
/usr/lib64/libBulletCollision.so.2.82 -> /usr/lib64/libBulletCollision.so.2.83
/usr/lib64/libBulletDynamics.so.2.82 -> /usr/lib64/libBulletDynamics.so.2.83
/usr/lib64/libBulletSoftBody.so.2.82 -> /usr/lib64/libBulletSoftBody.so.2.83
/usr/lib/64/libLinearMath.so.2.82 -> /usr/lib64/libLinearMath.so.2.83

Then install with: rpm -if --no-deps ./panda3d-XXX.rpm

Check afterwards if the install worked: python3 -c "import panda3d;" (must not throw an error - if it does, there are other dependencies actually missing and you have to install them properly first)

Oops, I missed your comment there!

Looking for that didn't occur to me because I git pulled a new revision and the build took really long as a usual from-scratch build... but I just removed built and started a build from scratch, and indeed you were right and this bug is just me being silly. Also, I have to admit I didn't run into this trap for the first time. Sorry!
