​I get "/usr/local/bin/perl5​". But this is broken, because of a missing
library:

$ ldd /usr/local/redhat/packages/local/bin/perl5.00503
        linux-gate.so.1 =>  (0xffffe000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x00bf1000)
        libdb.so.3 => not found
        libgdbm.so.2 => /usr/lib/libgdbm.so.2 (0xf7eb1000)
        libdl.so.2 => /lib/libdl.so.2 (0x00810000)
        libm.so.6 => /lib/libm.so.6 (0x00833000)
        libc.so.6 => /lib/libc.so.6 (0x006b4000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xf7e7e000)
        /lib/ld-linux.so.2 (0x00691000)

​And it will error out as:

"error while loading shared libraries: libdb.so.3: cannot open shared
object file: No such file or directory"​

​If I run the snippet with perl5 replaced with perl it will run fine with
following output:

./
../
username/
ok
​
​Yeah! now we know Perl package is the problem. What I have to do so that
tram uses "perl" instead of "perl5". You really helped in pinpointing the
issue with great precision!

Best regards, Michael.
