# zip
exec(): 0509-036 Cannot load program zip because of the following errors:
0509-022 Cannot load module /opt/freeware/lib/libbz2.a(libbz2.so.1).
0509-150 Dependent module libgcc_s.a(shr.o) could not be loaded.
0509-022 Cannot load module libgcc_s.a(shr.o).
0509-026 System error: A file or directory in the path name does not exist.
0509-022 Cannot load module zip.
0509-150 Dependent module /opt/freeware/lib/libbz2.a(libbz2.so.1) could not be loaded.

"LIBPATH=/opt/freeware/lib zip" works.

Package differences are:

I am having the same issue - however my AIX 7.1 system had no updates to gcc- but did have updates to bzip2. 

My updates:

Updating   : sudo-1.8.27-3.ppc   
Updating   : gzip-1.10-1.ppc     
Updating   : less-551-1.ppc      
Updating   : db-6.2.38-1.ppc     
Updating   : bzip2-1.0.8-1.ppc   
Updating   : ruby-2.6.3-1.ppc    
Updating   : rsync-3.1.3-4.ppc   
Updating   : pysqlite-2.8.3-2.ppc

I suspect the issue may be with bzip2? When I downdated bzip2 to 1.0.6-2 it fixed zip for me.

Downgrading bzip2 to 1.0.6-3 fixed my problem as well. Thanks!

The new bzip2 1.0.8 is built using gcc and the library search path is not properly set during compilation.

We will fix this and publish a new release soon.
