ups-nut-usb is linking to "<horizontal tab>libusb-1.0"

[gkoh]

I'm running pkgsrc on OmniOS v11 r151022ax.
Currently on 2018Q1 with following package versions:

• ups-nut-2.6.5nb1
• ups-nut-usb-2.6.5nb3
• libusb-compat-0.1.6rc2
• libusb1-1.0.21

When running usbhid-ups directly (to debug), get this:

# /opt/local/libexec/nut/usbhid-ups 
libusb-compat: error while loading 	libusb-1.0.so.0 from libusb-0.1.so.4: ld.so.1: usbhid-ups: fatal: 	libusb-1.0.so.0: open failed: No such file or directory

An ldd shows nothing weird:

# ldd /opt/local/libexec/nut/usbhid-ups 
	libusb-0.1.so.4 =>	 /opt/local/lib//libusb-0.1.so.4
	libdl.so.1 =>	 /lib/64/libdl.so.1
	libsocket.so.1 =>	 /lib/64/libsocket.so.1
	libnsl.so.1 =>	 /lib/64/libnsl.so.1
	libumem.so.1 =>	 /lib/64/libumem.so.1
	libssp.so.0 =>	 /opt/local/gcc49/x86_64-sun-solaris2.11/lib/amd64/libssp.so.0
	libc.so.1 =>	 /lib/64/libc.so.1
	libgcc_s.so.1 =>	 /opt/local/gcc49/x86_64-sun-solaris2.11/lib/amd64/libgcc_s.so.1
	libmp.so.2 =>	 /lib/64/libmp.so.2
	libmd.so.1 =>	 /lib/64/libmd.so.1
	libm.so.2 =>	 /lib/64/libm.so.2

Finally got the root cause with truss:

# truss /opt/local/libexec/nut/usbhid-ups
...
stat("/opt/local/lib//\x09libusb-1.0.so.0", 0xFFFFFD7FFFDFECA0) Err#2 ENOENT
stat("/opt/local/gcc49/x86_64-sun-solaris2.11/lib/amd64/\x09libusb-1.0.so.0", 0xFFFFFD7FFFDFECA0) Err#2 ENOENT
stat("/opt/local/gcc49/lib/gcc/x86_64-sun-solaris2.11/4.9.4/\x09libusb-1.0.so.0", 0xFFFFFD7FFFDFECA0) Err#2 ENOENT
stat("/opt/local/lib/\x09libusb-1.0.so.0", 0xFFFFFD7FFFDFECA0) Err#2 ENOENT
stat("/lib/64/\x09libusb-1.0.so.0", 0xFFFFFD7FFFDFECA0) Err#2 ENOENT
stat("/usr/lib/64/\x09libusb-1.0.so.0", 0xFFFFFD7FFFDFECA0) Err#2 ENOENT
...

Hmm, it's looking for libusb-1.0 prefixed with ASCII 0x09 == HT == horizontal tab, no wonder I can't 'see' the problem!

I can work around this by doing:

# ln -s libusb-1.0.so.0 "`echo -e '\tlibusb-1.0.so.0'`"

And bingo, now it finds the library and errors normally:

# /opt/local/libexec/nut/usbhid-ups 
Network UPS Tools - Generic HID driver 0.37 (2.6.5)
USB communication driver 0.31
Error: specifying '-a id' is now mandatory. Try -h for help.

Thanks for finding this, sorry it took so long to fix. This has been resolved and will be in 2018Q3.
