Hi !

I installed gazebo11 on Mac OSX 10.15.4 using the default installation one liner script here: http://gazebosim.org/tutorials?tut=install_on_mac&cat=install#Alternativeinstallation:step-by-step

Everything seems to install properly, but I get this error when I attempt to run Gazebo:

MacBook-Pro:~ myhostname$ gazebo

dyld: Library not loaded: /usr/local/opt/bullet/lib/libBulletSoftBody.2.88.dylib Referenced from: /usr/local/bin/gazebo Reason: image not found Abort trap: 6

When I searched for libBulletSoftBody.2.88.dylib, I found libBulletSoftBody.2.89.dylib installed instead:

MacBook-Pro:lib myhostmane$ pwd /usr/local/opt/bullet/lib MacBook-Pro:lib myhostmane$ ls libBulletSoftBody.* libBulletSoftBody.2.89.dylib libBulletSoftBody.a libBulletSoftBody.dylib

The installation script installed 2.89:

==> Installing osrf/simulation/gazebo11 dependency: bullet ==> Downloading https://homebrew.bintray.com/bottles/bullet-2.89.catalina.bottle ==> Downloading from https://akamai.bintray.com/38/38cdb6c948cb2c75ad2d6640629f1

But the binary seems to be calling 2.88

MacBook-Pro:~ myhostname$ gazebo dyld: Library not loaded: /usr/local/opt/bullet/lib/libBulletSoftBody.2.88.dylib Referenced from: /usr/local/bin/gazebo Reason: image not found Abort trap: 6

How do I fix this ?

Thanks ! Brian
